MSM6691 ic equivalent, dram interface ic.
* DRAM (¥ 1-bit configuration)
* 1-Mbit DRAM (M 51100A, M511001A) : Four units can be used.
* 4-Mbit DRAM (M 514100A, M514101A) : Four units can be used.
.
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 MSM65.
