¡ Semiconductor MSM6691
¡ Semiconductor DRAM Interface IC
MSM6691
GENERAL DESCRIPTION
DRAMs can be used for voice storage by connecting the MSM6691 with OKI's integrate R/W (Read/Write) ICs, the MSM6388, and the MSM6588.
The MSM6691 translates the signals associated with the dedicated serial register interface of the MSM6388 and MSM6588 driver interface when used in a stand-alone mode.
