DR013-0B 10/17/2002 3 IC41C4405x and IC41LV4405x Series Functional Description Refresh Cycle The IC41C4405x and IC41LV4405x are CMOS DRAMs optimized for high-speed bandwidth, low power applications. During READ or WRITE cycles, each bit is uniquely addressed through the 11 or 12 address bits. These are entered 11 bits (A0-A10) at a time for the 2K refresh device or 12 bits (A0-A11) at a time for the 4K refresh device. The row address is latched by the Row Address Strobe (RAS). The column address is latched by the Column Address Strobe (CAS). RAS is used to latch the first nine bits and CAS is used the latter ten bits. To retain data, 2,048 refresh cycles are required in each 32 ms period, or 4,096 refresh cycles are required in each 64ms period. There are two ways to refresh the memory: 1. By clocking each of the 2,048 row addresses (A0 through A10) or 4096 row addresses (A0 through A11) with RAS at least once every 32 ms or 64ms respectively. Any read, write, read-modify-write or RAS-only cycle refreshes the addressed row. Memory Cycle A memory cycle is initiated by bring RAS LOW and it is terminated by returning both RAS and CAS HIGH. To ensures proper device operation and data integrity any memory cycle, once initiated, must not be ended or aborted before the minimum tRAS time has expired. A new cycle must not be initiated until the minimum precharge time tRP, tCP has elapsed. Read Cycle A read cycle is initiated by the falling edge of CAS or OE, whichever occurs last, while holding WE HIGH. The column address must be held for a minimum time specified by tAR. Data Out becomes valid only when tRAC, tAA, tCAC and tOEA are all satisfied. As a result, the access time is dependent on the timing relationships between these parameters. 2. Using a CAS-before-RAS refresh cycle. CAS-beforeRAS refresh is activated by the falling edge of RAS, while holding CAS LOW. In CAS-before-RAS refresh cycle, an internal 11(12)-bit counter provides the row addresses and the external address inputs are ignored. CAS-before-RAS is a refresh-only mode and no data access or device selection is allowed. Thus, the output remains in the High-Z state during the cycle. Power-On After application of the VCC supply, an initial pause of 200 µs is required followed by a minimum of eight initialization cycles (any combination of cycles containing a RAS signal). During power-on, it is recommended that RAS track with VCC or be held at a valid VIH to avoid current surges. Write Cycle A write cycle is initiated by the falling edge of CAS and WE, whichever occurs last. The input data must be valid at or before the falling edge of CAS or WE, whichever occurs last. 4 Integrated Circuit Solution Inc.

DR013-0B 10/17/2002 IC41C4405x and IC41LV4405x Series Notes: 1. An initial pause of 200 µs is required after power-up followed by eight RAS refresh cycle (RAS-Only or CBR) before proper device operation is assured. The eight RAS cycles wake-up should be repeated any time the tREF refresh requirement is exceeded. 2. VIH (MIN) and VIL (MAX) are reference levels for measuring timing of input signals. Transition times, are measured between VIH and VIL (or between VIL and VIH) and assume to be 1 ns for all inputs. 3. In addition to meeting the transition rate specification, all input signals must transit between VIH and VIL (or between VIL and VIH) in a monotonic manner. 4. If CAS and RAS = VIH, data output is High-Z. 5. If CAS = VIL, data output may contain data from the last valid READ cycle. 6. Measured with a load equivalent to one TTL gate and 50 pF. 7. Assumes that tRCD < tRCD (MAX). If tRCD is greater than the maximum recommended value shown in this table, tRAC will increase by the amount that tRCD exceeds the value shown. 8. Assumes that tRCD > tRCD (MAX). 9. If CAS is LOW at the falling edge of RAS, data out will be maintained from the previous cycle. To initiate a new cycle and clear the data output buffer, CAS and RAS must be pulsed for tCP. 10. Operation with 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, access time is controlled exclusively by tCAC. 11. Operation within the tRAD (MAX) limit ensures that tRCD (MAX) can be met. tRAD (MAX) is specified as a reference point only; if tRAD is greater than the specified tRAD (MAX) limit, access time is controlled exclusively by tAA. 12. Either tRCH or tRRH must be satisfied for a READ cycle. 13. tOFF (MAX) defines the time at which the output achieves the open circuit condition; it is not a reference to VOH or VOL. 14. tWCS, tRWD, tAWD and tCWD are restrictive operating parameters in LATE WRITE and READ-MODIFY-WRITE cycle only. If tWCS > tWCS (MIN), the cycle is an EARLY WRITE cycle and the data output will remain open circuit throughout the entire cycle. If tRWD > tRWD (MIN), tAWD > tAWD (MIN) and tCWD > tCWD (MIN), the cycle is a READ-WRITE cycle and the data output will contain data read from the selected cell. If neither of the above conditions is met, the state of I/O (at access time and until CAS and RAS or OE go back to VIH) is indeterminate. OE held HIGH and WE taken LOW after CAS goes LOW result in a LATE WRITE (OE-controlled) cycle. 15. Output parameter (I/O) is referenced to corresponding CAS input. 16. During a READ cycle, if OE is LOW then taken HIGH before CAS goes HIGH, I/O goes open. If OE is tied permanently LOW, a LATE WRITE or READ-MODIFY-WRITE is not possible. 17. Write command is defined as WE going low. 18. LATE WRITE and READ-MODIFY-WRITE cycles must have both tOD and tOEH met (OE HIGH during WRITE cycle) in order to ensure that the output buffers will be open during the WRITE cycle. The I/Os will provide the previously written data if CAS remains LOW and OE is taken back to LOW after tOEH is met. 19. The I/Os are in open during READ cycles once tOD or tOFF occur. 20. Determined by falling edge of CAS. 21. Determined by rising edge of CAS. 22. These parameters are referenced to CAS leading edge in EARLY WRITE cycles and WE leading edge in LATE WRITE or READMODIFY-WRITE cycles. 23. CAS must meet minimum pulse width. 24. The 3 ns minimum is a parameter guaranteed by design. 25. Enables on-chip refresh and address counters. Integrated Circuit Solution Inc.
