256K x 16 Bit 3.3 V Asynchronous
Fast Static RAM
The MCM6343 is a 4,194,304–bit static random access memory organized as
262,144 words of 16 bits. Static design eliminates the need for external clocks
or timing strobes.
The MCM6343 is equipped with chip enable (E), write enable (W), and output
enable (G) pins, allowing for greater system flexibility and eliminating bus con-
tention problems. Separate byte enable controls (LB and UB) allow individual
bytes to be written and read. LB controls the lower bits DQ0 to DQ7, while UB
controls the upper bits DQ8 to DQ15.
The MCM6343 is available in a 400 mil, 44–lead small–outline SOJ package
and a 44–lead TSOP Type II package.
