GENERAL DESCRIPTION
The MS82V48540 is a 48-Mbit system clock synchronous dynamic random access memory. In addition to the
conventional random read/write access function, the MS82V48540 provides the automatic row address increment
function and automatic bank switching function. Therefore, if once the row and column addresses are set,
continuous serial accesses are possible while banks are automatically switched till input of the Precharge
command. The MS82V48540 is ideal for digital camera and TV buffer memory applications.
