(?1 ?: odd, ?0 ?: even) err_out output active low parity error detected on the address and control bus. a resistor may be connected from err_out bus line to v dd on the system planar to act as a pull up. sa0~sa2 input - these signals are tied at the system to either v ss or v ddspd to configure the serial spd eeprom address range. sda input/ output - this bidirectional pin is used to transfer data into or out of the spd eeprom. an external resistor may be connected from the sda bus line to v ddspd to act as a pullup on the system board. scl input - this signal is used to clock data into and out of the spd eeprom. an external resistor may be connected from the scl bus tied to v ddspd to act as a pullup on the system board. event output active low this signal indicates that a thermal event has been detected in the thermal sensing device.the system should guarantee the electrical level requirement is met for the event pin on ts/spd part. no pull-up resister is provided on dimm. reset input active low asynchronous reset is active when reset is low, and inactive when reset is high. reset must be high during normal operation. reset is cmos rail to rail signal with dc high and low at 80% and 20% of v dd . v dd, v ss supply - power and ground for the ddr3 sdram input buffers, and core logic. v dd and v ddq pins are tied to v dd /v ddq planes on these modules. v ss pins are tied to v ss planes on these mod- ules. v ddq supply - power supply for the ddr3 sdram output buffe rs to provide improved noise immunity. v ddq shares the same power plane as v dd pins. v refdq supply reference voltage for i/o inputs. v refca supply - reference voltage for address/command inputs. v ddspd supply - power supply for spd eeprom. this supply is separate from the v dd /v ddq power plane. eeprom supply is operable from 1.7v to 3.6v. v tt supply - termination voltage for address/command/control/clock nets. nc - - no connect. sg5127rd325693uu april 9, 2010 corporate headquarters: p. o. box 1757, fremont, ca 94538, usa ?

(b) cke low is allowed only if tmrd and tmod are satisfied. notes: 1. cke (n) is the logic state of cke at clock edge n; cke (n-1) was the state of cke at the previous clock edge. 2. current state is defined as the state of the ddr3 sdram immediately prior to clock edge n. 3. command (n) is the command registered at clock edge n, and action (n) is a result of command (n), odt is not included here. 4. all states and sequences not shown are illegal or reserved unless explicitly described elsewhere in this document. 5. the state of odt does not affect the states described in this table. the odt function is not available during self-refresh. 6. cke must be registered with the same value on t cke min consecutive positive clock edges. cke must remain at the valid input level the entire time it takes to achieve the t cke min clocks of registration. thus, after any cke trans ition, cke may not transition from its valid level during the time period of t is + t cke min + t ih . 7. deselect and nop are defined in the command truth table. 8. on self-refresh exit, deselect or nop commands must be issued on every clock edge occurring during the t xs period. read or odt commands may be issued only after t xsdll is satisfied. 9. self-refresh mode can only be entered from the all banks idle state. 10. must be a legal command as defined in the command truth table. 11. valid commands for power-down entry and exit are nop and deselect only. 12. valid commands for self-refresh exit are nop and deselect only. 13. self-refresh can not be entered during read or write operations. 14. the power-down does not perform any refresh operations. 15. ?x? means ?don?t care? (including floating around v ref ) in self-refresh and power-down. it also applies to address pins. 16. v ref (both v refdq and v refca ) must be maintained during self-refresh operation. 17. if all banks are closed at the conclusion of the read, write or precharge command, then prechar ge power-down is entered, oth erwise active power-down is entered. 18. ?idle state? is defined as all banks are closed (t rp , t dal , etc. satisfied), no data bursts are in progress, cke is high, and all timings from previous operations are satisfied (t mrd , t mod , t rfc , t zqinit , t zqoper , t zqcs , etc.) as well as all self-refresh exit and power-down exit parameters are satisfied (t xs , t xp , t xpdll , etc.). current state cke command (n) 3 ras , cas , we , cs action (n) 3 notes previous cycle (n-1) current cycle (n) power-down l l x maintain power-down 14, 15 l h deselect or nop power-down exit 11, 14 self-refresh l l x maintain self-refresh 15, 16 l h deselect or nop self-refresh exit 8, 12, 16 bank activate h l deselect or nop active power-down entry 11, 13, 14 reading h l deselect or nop power-down entry 11, 13, 14, 17 writing h l deselect or nop power-down entry 11, 13, 14, 17 precharging h l deselect or nop power-down entry 11, 13, 14, 17 refreshing h l deselect or nop precharge power-down entry 11 all banks idle h l deselect or nop precharge power-down entry 11, 13, 14, 18 l refresh self-refresh 9, 13, 18 for more details with all signals, see command truth table on the previous pages. 10 sg5127rd325693uu april 9, 2010 corporate headquarters: p. o. box 1757, fremont, ca 94538, usa ?

and ?odt vol tage and temperature sensitivity? tables. the appropr iate interval between zqcs commands can be determined from these tables and other a ppli- cation-specific parameters. one method for calculating the interval between zqcs commands, given the temperature (tdriftrate) and voltage (vdriftrate) drif t rates that the sdram is subject to in the application, is illust rated. the interval could be defined by the following formula: where tsens = max(drttdt, drondtm) and vsens = max(drttdv, drondvm) define the sdram temperature and voltage sensitivi- ties. for example, if tsens = 1.5% / c, vsens = 0.15% / mv, tdriftrate = 1 c / sec and vdriftrate = 15 mv / sec, then the interval between zqcs commands is calculated as: 24. n = from 13 cycles to 50 cycles. this row defines 38 parameters. 25. t ch(abs) is the absolute instantaneous clock high pulse width, as measured from one rising edge to the following falling edge. 26. t cl(abs) is the absolute instantaneous clock low pulse width, as measured from one falling edge to the following rising edge. 27. the t is(base) ac150 specifications are adjusted from the t is(base) specification by adding an additional 100 ps of derating to accommodate for the lower alternate threshold of 150 mv and another 25 ps to account for the earlier reference point [(175 mv - 150 mv) / 1 v/ns]. 28. pulse width of a input signal is defined as the width between the first crossing of v refdc and the consecutive crossing of v refdc . zqcorrection tsens tdriftrate () vsens vdriftrate () + ------------------------------------------------------------------------------------------------------------------------ - 0.5 1.5 1 () 0.15 15 + () + ---------------------------------------------------------- - 0.133 128 ms = sg5127rd325693uu april 9, 2010 corporate headquarters: p. o. box 1757, fremont, ca 94538, usa ?

(output deratings are relative to the sdram input clock.) for example, if the measured jitter into a ddr3-800 sdram has t err(mper) act,min = - 172 ps and t err(mper) act,max = + 193 ps, then t dqsck min(derated) = t dqsck min - t err(mper) act,max = - 400 ps - 193 ps = - 593 ps and t dqsck max(derated) = t dqsck ,max - t err(mper) act,min = 400 ps + 172 ps = + 572 ps. similarly, t lz(dq) for ddr3-800 derates to t lz(dq) min(derated) = - 800 ps - 193 ps = - 993 ps and t lz(dq) max(derated) = 400 ps + 172 ps = + 572 ps. (caution on the min/max usage!) note that t err(mper) act,min is the minimum measured value of t err(nper) where 2 n 12, and t err(mper) act,max is the maximum mea- sured value of t err(nper) where 2 n 12. b when the device is operated with input clock jitter, this parameter needs to be derated by the actual t jit(per) ,act of the input clock. (output deratings are relative to the sdram input clock.) for example, if the measured jitter into a ddr3-800 sdram has t ck(avg) act = 2500 ps, t jit(per) act,min = - 72 ps and t jit(per) act,max = + 93 ps, then t rpre min(derated) = t rpre min + t jit(per) act,min = 0.9 x t ck(avg) act + t jit(per) act,min = 0.9 x 2500 ps - 72 ps = + 2178 ps. similarly, t qh min(derated) = t qh min + t jit(per) act,min = 0.38 x t ck(avg) act + t jit(per) act,min = 0.38 x 2500 ps - 72 ps = + 878 ps. (caution on the min/max usage!) c these parameters are measured from a data strobe signal (dqs, dqs ) crossing to its respective clock signal (ck, ck ) crossing. the spec values are not affected by the amount of clock jitter applied (i.e. tjit(per), tjit(cc), etc.), as these are relative to the cl ock signal crossing. that is, these parameters should be met w hether clock jitter is present or not. d these parameters are measured from a data signal (dm, dq0, dq1, etc.) transition edge to its respective data strobe signal (dq s, dqs ) crossing. e for these parameters, the ddr3 sdram device supports t nparam [nck] = ru{t param [ns] / t ck(avg) [ns]}, which is in clock cycles, assuming all input clock jitter specifications are satisfied. for example, the device will support t nrp = ru{t rp / t ck(avg) }, which is in clock cycles, if all input clock jitter specifications ar e met. this means: for ddr3-800 6-6-6, of which t rp = 15ns, the device will support t nrp = ru{t rp / t ck(avg) } = 6, as long as the input clock jitter specifications are met, i.e. precharge command at tm and active command at tm+6 is valid even if (tm+6 - tm) is less than 15 ns due to input clock jitter. sg5127rd325693uu april 9, 2010 corporate headquarters: p. o. box 1757, fremont, ca 94538, usa ? tel:(510) 623-1231 ? fax:(510) 623-1434 ? e-mail: info@smartm.com europe: 5 kelvin park south, kelvin south, east kilbride, g75 orh, united kingdom ? tel: +44-870-870-8747 ? fax: +44-870-870-8757 asia/pacific: plot 18, lrg jelawat 4, kawasan perindustrian seberang jaya 13700, prai, penang, malaysia ? tel: +604-3992909 ? fax: +604-3992 903 44 part number decode 1 smart modular technologies 2 module process technology g: green module (rohs compliant) 3 module address depth 512: 512m 4 module data bus width 7: x72 5 module configuration rd3: ddr3 registered dimm 6 device configuration 256: 256mx4 7 cas latency 9: cl 9.0 8 module speed 3: ddr3-1333 9 device vendor h: hynix s: samsung 10 device revision b: revision b e: revision e f: revision f t: revision t s g 512 7 rd3 256 9 3 u u 12 3 4 5 6 78910 note: ?uu? in the part number should be replaced by user specified option. sg5127rd325693uu april 9, 2010 corporate headquarters: p. o. box 1757, fremont, ca 94538, usa ? tel:(510) 623-1231 ? fax:(510) 623-1434 ? e-mail: info@smartm.com europe: 5 kelvin park south, kelvin south, east kilbride, g75 orh, united kingdom ? tel: +44-870-870-8747 ? fax: +44-870-870-8757 asia/pacific: plot 18, lrg jelawat 4, kawasan perindustrian seberang jaya 13700, prai, penang, malaysia ? tel: +604-3992909 ? fax: +604-3992 903 45 disclaimer: no part of this document may be copied or reproduced in any form or by any means, or transferred to any third party, without the prior written consent of an authorized representative of smart modular technologies, inc.
