DESCRIPTION
PINCONFIGURATION
(TOP VIEW)
1. 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
2. large-capacity memory systems where high speed, low power dissipation, and
low cost are essential. The use of quadruple-layer polysilicon process combined

# 70-pin,400-mil TSOP (type II ) with 0.65mm
lead pitch and 23.49mm package length.
# Multiplexed DRAM address inputs for reduced pin
count and higher system densities.
# Selectable output operation (transparent / latched /
registered) using set command register cycle.
# Single 3.3V +/- 0.3V Power Supply.
(3.3V +/- 0.15V for -7 part)
# 2048 refresh cycles every 64ms (Ad0->Ad10).
# Programmable burst length (1,2,4,8) and burst
sequence (sequential,interleave) with no latency.
# Synchronous design for precise control with
an external clock (K).
# Output retention by advanced mask clock (CMs#).
# All inputs/outputs low capacitance and LVTTL
compatible.
# Separate DRAM and SRAM address inputs
for fast SRAM access.
# Page Mode capability.
# Auto Refresh capability.
# Self Refresh capability.
