Additional Details:

The MN41256-12 operates on a single +5V power supply. It utilizes a multiplexed address scheme, where row and column addresses are time-multiplexed on the same address pins. This feature minimizes the number of pins required, enabling a smaller package size. The device supports standard DRAM refresh cycles to maintain data integrity. It is available in a DIP (Dual In-line Package).
