General Description
The UM2332 is a 32,768-bit static MOS read only memory
organized as 4096 words by 8 bits. The device is com-
pletely static in operation, and operates from a single
+5V power supply. All inputs and outputs are TT L com-
patible. The two chip select inputs are programmable.
Programming of the device is accomplished by a custom
masking process. The UM2332 is designed for memory
application~ where high performance, large bit storage,
and simple interfacing are important· design objectives.
