Address Inputs  
Data In/Data Out  
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.
