Summary :

A GTL/LV-CMOS interfaced 1 M bit(32k words 36bits/64k words18bits) BiCMOS cache SRAM is designed within a 5.65 10.54mm2 chip size. The process is 0.4µm BiCMOS with 4 poly-Si layers, 3 Metal layers, and TFT memory cells(2.66 4.94µm2). The late write operation is newly adopted. The late write operation method improvements make the fast access time 6 ns and the shorter cycle time 5 ns.
