Description

The Fujitsu MB81C4256A electronic component model is a CMOS, fully decoded dynamic RAM. It is organized as 262,144 words x 4 bits. This model is designed for various applications including mainframe memories, buffer memories, video image memories requiring high speed and high-band width output with low power dissipation. It is also suitable for memory systems of handheld computers that require very low power dissipation.

One of the key features of the MB81C4256A is Fujitsu's advanced three-dimensional stacked capacitor cell technology, which provides high α-ray soft error immunity and extended refresh time. Additionally, CMOS technology is used in the peripheral circuits to offer low power dissipation and high-speed operation.
