The DIMMs use sixteen 4M x 4 EDO DRAMs for the 4M x 64 organisation and eighteen 4M x 4 DRAMs for the 4M x 72 organisation, both in TSOPII packages. Decoupling capacitors are mounted on the PC board. The DIMMs use optional serial presence detects implemented via a serial E 2PROM using the two pin I2C protocol. The first 128 bytes are utilized by the DIMM manufacturer and the second 128 bytes of serial PD data are available to the customer. All 168-pin DIMMs provide a high performance, flexible 8-byte interface in a 133,35 mm long spacesaving footprint.

Specified values are obtained with the output open. 4) Address can be changed once or less while RAS = Vil. In case of ICC4 it can be changed once or less during a hyper page mode (EDO) cycle 5) An initial pause of 200 s is required after power-up followed by 8 RAS cycles of which at least one cycle has to be a refresh cycle, before proper device operation is achieved. In case of using the internal refresh counter, a minimum of 8 CAS-before-RAS initialization cycles instead of 8 RAS cycles are required. 6) AC measurements assume tT = 2 ns. 7) VIH (min.) and VIL (max.) are reference levels for measuring timing of input signals. Transition times are also measured between VIH and VIL. 8) Measured with the specified current load and 100 pF at Vol = 0.8 V and Voh = 2.0 V. Access time is determined by the latter of t RAC, tCAC, tAA,tCPA ,tOEA. t CAC is measured from tristate. 9) Operation within the tRCD (max.) limit ensures that tRAC (max.) can be met. tRCD (max.) is specified as a reference point only. If tRCD is greater than the specified tRCD (max.) limit, then access time is controlled by tCAC. 10) Operation within the tRAD (max.) limit ensures that tRAC (max.) can be met. tRAD (max.) is specified as a reference point only. If tRAD is greater than the specified tRAD (max.) limit, then access time is controlled by tAA. 11) Either tRCH or tRRH must be satisfied for a read cycle. 12) tOFF (max.), tOEZ (max.) define the time at which the output achieves the open-circuit conditions and are not referenced to output voltage levels. tOFF is referenced from the rising edge of RAS or CAS, whichever occurs last. 13) Either tDZC or tDZO must be satisfied. 14) Either tCDD or tODD must be satisfied. 15) tWCS , tRWD , tCWD and tAWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If tWCS > tWCS (min.) , the cycle is an early write cycle and data out pin will remain open-circuit (high impedance) through the entire cycle; if tRWD > tRWD (min.) , tCWD > tCWD (min.) and tAWD > tAWD (min.) , the cycle is a read-write cycle and I/O will contain data read from the selected cells. If neither of the above sets of conditions is satisfied, the condition of I/O (at access time) is indeterminate. 16) These parameters are referenced to the CAS leading edge in early write cycles and to the WE leading edge in read-write cycles.

Information about the modul confuguration, speed, etc. is written into the EEPROM device during module production using a serial presence detect protocol ( I 2C synchronous 2-wire bus). 64 V4005 GU-50 0 Number of SPD bytes 128 80 1 Total bytes in Serial PD 256 08 2 Memory Type EDO 02 3 Number of Row Addresses 11 0B 4 Number of Column Addresses 11 0B 5 Number of DIMM Banks 1 01 6 Module Data Width x64 / x72 40 7 Module Data Width (cont' d) 0 00 8 Module Interface Levels LVTTL 01 9 RAS access time 50 / 60 ns 32 10 CAS access time 13 / 15 ns 0D 11 Dimm Config (Error Det/Corr.) none / ECC 00 12 Refresh Rate/Type normal 00 15.6s 13 Primary DRAM data width x4 04 14 Error checking DRAM data width none / x4 00 15-31 reserved for future offerings FF 32 Superset Memory Type NA FF 33-61 Superset information (may be used in NA FF future) 62 SPD Revision Designator Rev. 1.0 01 63 Checksum for bytes 0-62 XX 64-127 Manufacturer Information (optional) FF 128- Unused Storage Locations FF 255 Byte# Description SPD Entry Value Hex HYM 64 V4005 GU-60 80 08 02 0B 0B 01 40 00 01 3C 0F 00 00 04 00 FF FF FF 01 03 FF FF 72 V4005 GU-50 80 08 02 0B 0B 01 48 00 01 32 0D 02 00 04 04 FF FF FF 01 05 FF FF 72 V4005 GU-60 80 08 02 0B 0B 01 48 00 01 3C 0F 02 00 04 04 FF FF FF 01 11 FF FF Semiconductor Group 15 HYM64(72)V4005/45GU-50/-60 4M x 64/72 DRAM Module Serial Presence Detects (cont' ): d 64 V4045 GU-50 0 Number of SPD bytes 128 80 1 Total bytes in Serial PD 256 08 2 Memory Type EDO 02 3 Number of Row Addresses 12 0C 4 Number of Column Addresses 10 0A 5 Number of DIMM Banks 1 01 6 Module Data Width x64 / x72 40 7 Module Data Width (cont' d) 0 00 8 Module Interface Levels LVTTL 01 9 RAS access time 50 / 60 0 ns 32 10 CAS access time 13 / 150 ns 0D 11 Dimm Config (Error Det/Corr.) none / ECC 00 12 Refresh Rate/Type normal 00 15.6s 13 Primary DRAM Organisation x4 04 14 Secondary DRAMOrgansation undefined 00 15-31 reserved for future offerings FF 32 Superset Memory Type NA FF 33-61 Superset information (may be used in NA FF future) 62 SPD Revision Designator Rev. 1.0 01 63 Checksum for bytes 0-62 XX 64-127 Manufacturer Information (optional) FF 128- Unused Storage Locations FF 255 Byte# Description SPD Entry Value Hex HYM 64 V4045 GU-60 80 08 02 0C 0A 01 40 00 01 3C 0F 00 00 04 00 FF FF FF 01 03 FF FF 72 V4045 GU-50 80 08 02 0C 0A 01 48 00 01 32 0D 02 00 04 00 FF FF FF 01 XX FF FF 72 V4045 GU-60 80 08 02 0C 0A 01 48 00 01 3C 0F 02 00 04 00 FF FF FF 01 0D FF FF Semiconductor Group 16 HYM64(72)V4005/45GU-50/-60 4M x 64/72 DRAM Module L-DIM-168-12 Module package (168 pin, dual read-out, single in-line memory module) 133,35 127,35 5,3 * 1 10 11 42,18 66,68 A B C 3,0 40 41 84 85 94 95 124 125 168 * * On x72 only (CB0-CB7) 6,35 3,125 3,125 6,35 1,27 2,54 min. 1,0 + 0.5 - 2,0 Detail A Detail B 2,0 Detail C DM168-12.WMF preliminary drawing Semiconductor Group 17 17,78 0,2 + 0,15 - 25,40 |
