Additional Details:

The UPD41464C-15 DRAM requires refresh cycles to retain stored data; this is inherent to DRAM technology. The operating temperature is generally between 0°C and 70°C. Handle this device carefully to prevent damage from electrostatic discharge (ESD). Refer to the manufacturer's datasheet for detailed electrical and timing specifications. Multiplexed address inputs help to reduce the number of address pins needed.
