.在5伏电源下
功率延迟积为0.036PJ/bit
最大工作电流为1.2mA
最大静态漏电流为0.1μA.采用一种新颖的灵敏放大器有效地提高了ROM的访问速度
ROM的访问时间为36ns.
The ASIC design of a 4K bit mask-programmable CMOS ROM is introduced
and the ROM has a small area of 0.082mm

with a power-delay product of 0.036PJ/bit.The high packing density and the excellent power-delay product have been achieved by using double well
single polysilicon
double metal 0.6μm CMOS technology and a serial ROM cell structure.The power supply currents in active and quiescent modes are 1.2mA and less than 0.1μA at +5V
respectively.Using a novel and simple sensitive amplifier/driver structure efficiently reduces the memory access time.The memory access time is 36ns.
