4,194,304-word x 1-bit Serial Register
This version: Feb. 1999

Previous version: May. 1997
GENERAL DESCRIPTION
MSM66V84B is a serial register organized as 4,194,304 words x one bit, characterized by medium-
speed, low power consumption operation.
This device has a built-in internal address generation circuit allowing continuous serial read/write
operation by external clock input.
Read/write operation causes the internal address to be incremented automatically by +1.
External address input enables addressing in units of 1024 words. Furthermore, a refresh timer and
a refresh address counter are installed, which makes an external refresh circuit unnecessary. In
addition, this configuration allows lower power consumption.
The device is packaged in 26/20-pin SOJ or 26/20 TSOP having a width of 300 mil.
It is well adapted for storing much data by means of a battery backup. Its combination with our
recording and playback LSI enables the easy implementation of a solid recording and playback
system.
