2-Mbit Serial Voice ROM
GENERAL DESCRIPTION
The MSM6596A is the shorter-TAT processing version of the MSM6596.
The MSM6596A is a serial voice ROM with a 1,048,576-word ¥ 1-bit ¥ 2-bank configuration.
The MSM6596A has a built-in internal address-generating circuit. A single, external clock input
allows continuous, serialreadoperations. Theinternaladdressesareautomaticallyincremented
by 1 by read operation. 1024 words in X direction and 1024 words in Y direction can be addressed
by inputting external serial addresses. Banks are switched with CS1 and CS2.
A read and playback device with predetermined messages can easily be configured by storing the
voice data into the MSM6596A and combining it with one of OKI's recording and playback ICs and
serial register IC.

does not operate without a serial register.)
The major functional differences between the MSM6596A and MSM6596 are shown below.
