GENERAL DESCRIPTION

The MSM6685A is a serial register composed of 8,388,608 words x one bit, characterized by mediumspeed, 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.
