PRELIMINARY
PDM31098
4 Megabit 3.3V Static RAM
Description
1Mx 4-Bit
1
The PDM31098 is a high-performance CMOS static
RAMs organized as 1,048,576 x 4 bits. Writing is
2 accomplished when the write enable (WE) and chip
enable CE inputs are both LOW. Reading is
accomplished when WE remains HIGH and OE and
CE are both LOW.
3 The PDM31098 operates from a single +3.3V power
supply and all the inputs and outputs are fully TTL-
compatible.
4 The PDM31098 is available in a 32-pin 400-mil plas-
tic SOJ package.
