The TMS41x409A and TMS42x409A series are
16777216-bit dynamic random-access memory
(DRAM) devices organized as 4194304 words of
four bits each.
These devices feature maximum RAS access
times of 50, 60, and 70 ns. All address and data-in
lines are latched on chip to simplify system
design. Data out is unlatched to allow greater
system flexibility.
