... The OKI MSM5412222 is a high performance 3-Mbit, 256K ¥ 12-bit, Field Memory especially designed for high-speed serial access applications such as HDTVs, conventional NTSC TVs, VTRs, digital movies and Multi-media systems. MSM5412222 is a FRAM for wide or low end use in general commodity TVs and VTRs exclusively. MSM5412222 is not designed for high end use in medical systems, professional graphics systems which require long term picture storage, data storage systems and others ...

... DRAM array, an RSTW operation is required after the last SWCK cycle. Note that every write timing of MSM5412222 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 ...

... OE is used to enable/disable the outputs. OE high level enables the outputs. The internal read address pointer is always incremented by cycling SRCK regardless of the OE level. Note that OE setup and hold times are referenced to the rising edge of SRCK. and t ) and RE hold times (t RENS RDSS MSM5412222 and RENH 6/15 ...

... It may be “old data” or “new” data combination of old and new data. Such a timing should be avoided. Cascade Operation The MSM5412222 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.
