... DRAM array, an RSTW operation is required after the last SWCK cycle. Note that every write timing of MSM518222A is delayed by one clock compared with read timings for easy cascading without any interface delay devices. Write Reset : RSTW The first positive transition of SWCK after RSTW becomes high resets the write address counters to zero ...

... The three-state output buffer provides direct TTL compatibility (no pullup resistor required). Data out is the same polarity as data in. The output becomes valid after the access time interval t begins with the rising edge of SRCK. *There are no output valid time restrictions on MSM518222A. Read Enable : RE The function gate the SRCK clock for incrementing the read pointer ...

... It may be "old data" or "new" data combination of old and new data. Such a timing should be avoided. Cascade Operation The MSM518222A is designed to allow easy cascading of multiple memory devices. This provides higher storage depth longer delay than can be achieved with only one memory device.
