1 / 37 page The TMS41x409A and TMS42x409A series are 16 777 216-bit dynamic random-access memory (DRAM) devices organized as 4 194 304 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. description TMS416409A, TMS417409A, TMS426409A, TMS427409A 4194304 BY 4-BIT EXTENDED DATA OUT DYNAMIC RANDOM-ACCESS MEMORIES SMKS893B – AUGUST 1996 – REVISED APRIL 1997 1 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251–1443 This data sheet is applicable to all TMS41x409As and TMS42x409As symbolized by Revision “B”, Revision “E”, and subsequent revisions as described in the device symbolization section.
