Serial writing in and serial reading from the MSM5424331 are performed line by line. In the FIFO mode, any line can be selected by specifying their addresses by the Serial Address input. In the Block Access mode, any line or word address (10 bits) can be set by entering the address through the address multiplexer. As the MSM5424331 in the Block Access mode can be controlled by RAS and CAS signals, it can easily interface to the MPU. The MSM5424331 contains dynamic memory cells. In the FIFO mode, the memory cells are automatically refreshed by the self refresh control circuit, but in the Block Access mode, the memory cells must be refreshed by the CAS before RAS Refresh function. The MSM5424331 is not designed for high end use in such applications as medical systems, professional graphics systems which require long term picture storage, data storage systems and others. 1/34 www.DataSheet4U.com FEDS5424331-01 1 Semiconductor MSM5424331 FEATURES • Switching between FIFO and Block Access modes by the D/F pin FIFO mode: Se.
