1-Mbit Serial Voice ROM
GENERAL DESCRIPTION
The MSM6595A is a MSM6595 short TAT process version.
The MSM6595A is a serial voice ROM with a 1,048,576-word ¥ 1-bit configuration.
The MSM6595A has a built-in internal address-generating circuit. A single, external clock input
allows continuous, serial read operations. The internal addresses are automatically incremented by
1 by read operation. 1024 words in X direction and 1024 words in Y direction can be addressed by
inputting external serial addresses. A read and playback device with predetermined messages can

recording and playback ICs and a serial register IC.

does not operate without a serial register.)
The major differences between the MSM6595A and MSM6595 are shown below.
