A start-up delay of 200 s is required after power-up, followed by a minimum of eight initialization cycles (RAS-only refresh or CAS before RAS refresh) before proper device operation is achieved. 2. The AC characteristics assume tT = 5 ns. 3. VIH (Min.) and VIL (Max.) are reference levels for measuring input timing signals. Transition times (tT) are measured between VIH and VIL. 4. This parameter is measured with a load circuit equivalent to 2 TTL loads and 100 pF. 5. 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 the access time is controlled by tCAC. 6. 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 the access time is controlled by tAA. 7. tCEZ (Max.), tREZ (Max.), tWEZ (Max.) and tOEZ (Max.) define the time at which the output achieves the open circuit condition and are not referenced to output voltage levels. 8. tCEZ and tREZ must be satisfied for open circuit condition. 9. tRCH or tRRH must be satisfied for a read cycle. 10. tWCS, tCWD, tRWD, tAWD and tCPWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If tWCS tWCS (Min.), then the cycle is an early write cycle and the data out will remain open circuit (high impedance) throughout the entire cycle. If tCWD tCWD (Min.) , tRWD tRWD (Min.), tAWD tAWD (Min.) and tCPWD tCPWD (Min.), then the cycle is a read modify write cycle and data out will contain data read from the selected cell; if neither of the above sets of conditions is satisfied, then the condition of the data out (at access time) is indeterminate. 11. These parameters are referenced to the CAS leading edge in an early write cycle, and to the WE leading edge in an OE control write cycle, or a read modify write cycle. 12. The test mode is initiated by performing a WE and CAS before RAS refresh cycle. This mode is latched and remains in effect until the exit cycle is generated. In a test mode CA0, CA1 and CA10 are not used and each DQ pin now accesses 8-bit locations. Since all 2 DQ pins are used, a total of 16 data bits can be written in parallel into the memory array. In a read cycle, if 8 data bits are equal, the DQ pin will indicate a high level. If the 8 data bits are not equal, the DQ pin will indicate a low level. The test mode is cleared and the memory device returned to its normal operating state by performing a RASonly refresh cycle or a CAS before RAS refresh cycle. 13. In a test mode read cycle, the value of access time parameters is delayed for 5 ns for the specified value. These parameters should be specified in test mode cycle by adding the above value to the specified value in this data sheet. 14. These parameters are determined by the falling edge of either CAS1 or CAS2, whichever is earlier. 15. These parameters are determined by the rising edge of either CAS1 or CAS2, whichever is later. 16. tCWL should be satisfied by both CAS1 and CAS2. 17. tCP is determined by the time both CAS1 and CAS2 are high. 8/18 Semiconductor Notes concerning CAS1 and CAS2 control MSM519205 Overlap the active-low timings of CAS1 and CAS2. Skew between CAS1 and CAS2 is allowed under the following conditions: (1) The timing specification for CAS1 and CAS2 should be met individually. (2) Different operation modes for CAS1/CAS2 are not allowed (as shown below). RAS CAS1 Delayed write CAS2 Early write WE (3) Closely separated CAS1/CAS2 control is not allowed. However, when the condition (tCP tUL) is satisfied, fast page mode can be performed.
