An 80 ns 1 Mbit MASK ROM with a new memory cell

A high-speed 1-Mb MASK ROM incorporating a new through-hole programmed memory cell, named THOLE CELL, and a full CMOS static sense amplifier is described. The ROM has been fabricated using a double-polysilicon p-well CMOS technology. As a result of achieving a compact ROM cell that is as small as 5.2-/spl times/6.4 /spl mu/m/SUP 2/, even with relatively… CONTINUE READING
