NTE6508
Integrated Circuit
CMOS, 1K Static RAM (SRAM)
Description:
The NTE6508 is a 1024 x 1 fully static CMOS RAM in a 16–Lead DIP type package fabricated using
self–aligned silicon gate technology. Synchronous circuit design techniques are employed to acheive
high performance and low power operation. On chip latches are provided for address allowing effeci-
ent interfacing with microprocessor systems. The data output buffers can be forced to a high imped-
ance state for use in expanded memory arrays.
