M5M4V16169DRT-8

The M5M4V16169DTP/RT is a 16M-bit Cached DRAM which integrates input registers, a 1,048,576-word by 16-bit dynamic memory array and a 1024- word by 16-bit static RAM array as a Cache memory (block size 8x16) onto a single monolithic circuit. The block data transfer between the DRAM and the data transfer buffers (RB1/RB2/WB1/WB2) is performed in one instruction cycle, a fundamental advantage over a conventional DRAM/SRAM cache.

The RAM is fabricated with a high performance CMOS process, and is ideal for large-capacity memory systems where high speed, low power dissipation, and low cost are essential. The use of quadruple-layer polysilicon process combined with silicide and double layer aluminum wiring technology, a single-transistor dynamic storage stacked capacitor cell, and a six-transistor static storage cache cell provide high circuit density at reduced costs.
