DESCRIPTION
The Fujitsu MB81V4260S is a fully decoded CMOS Dynamic RAM (DRAM) that contains 4,194,304 memory
cells accessible in 16-bit increments. The MB81V4260S features a “fast page” mode of operation whereby high-
speed access of up to 512
×
16-bits of data can be selected in the same row. The MB81V4260S-60/-70 DRAMs
are ideally suited for memory applications such as embedded control, buffer, portable computers, and video
imaging equipment where very low power dissipation and high bandwidth are basic requirements of the design.
The MB81V4260S is fabricated using silicon gate CMOS and Fujitsu’s advanced four-layer polysilicon process.
This process, coupled with three-dimensional stacked capacitor memory cells, reduces the possibility of soft
errors and extends the time interval between memory refreshes.
