M5M5255DP-70XL

'97.4.7 MITSUBISHI LSIs M5M5255DP,FP -45LL,-55LL,-70LL, -45XL,-55XL,-70XL 262,144-BIT (32,768-WORD BY 8-BIT) CMOS STATIC RAM DESCRIPTION The M5M5255DP,FP 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. It is ideal for the memory systems which require simple interface.
