Additional Details

The UPD4564163G5-A80-9JF is specifically designed for use in systems that require fast and efficient graphics memory. Write per bit control is a key feature, offering increased flexibility and performance in handling pixel data and other graphical elements. It improves memory bandwidth efficiency by only modifying the bits that need to change, preventing unnecessary writes and power consumption. Always refer to the NEC datasheet for exact specifications, timing parameters, and voltage levels.

This SGRAM requires careful handling and ESD protection during installation and operation. Design engineers should consult the datasheet for detailed information on power supply requirements, signal timing, and thermal considerations.
