description
The and TMS465169 is a high-speed,
67108864-bit dynamic random-access memory
(DRAM) device organized as 4194304 words of
16 bits. The TMS465169P is similar DRAM but
includes a long refresh period and a self-refresh
option. Both employ state-of-the-art technology
for high performance, reliability, and low power at
low cost.
