... M5M5256DFP,VP,RV -10VLL,-12VLL,-15VLL, DESCRIPTION The M5M5256DFP,VP,RV is 262,144-bit CMOS static RAMs organized as 32,768-words by 8-bits which is fabricated using high-performance 3 polysilicon CMOS technology. The use of resistive load NMOS cells and CMOS periphery results in a high density and low power static RAM. Stand-by current is small enough for battery back-up application ...

... M5M5256DFP,VP,RV -10VLL,-12VLL,-15VLL, FUNCTION The operation mode of the M5M5256DP,FP,VP,RV is determined by a combination of the device control inputs /S, /W and /OE. Each mode is summarized in the function table. A write cycle is executed whenever the low level /W overlaps with the low level /S. The address must be set up before the write cycle and must be stable during the entire cycle ...
