Additional Details:

The MT4C4256Z-8 requires a refresh cycle to maintain data integrity. It operates from a 5V power supply. The chip is typically available in a DIP (Dual In-Line Package) or SOJ (Small Outline J-lead) package. The 80ns access time refers to the time it takes for the memory to retrieve data after receiving a read command. It is a widely used DRAM chip in legacy systems and older electronic devices. The device is designed for stable operation in a range of environmental conditions.
