Features, Applications


This is a family by 4-bit dynamic RAMS, fabricated with the high performance CMOS process,and is ideal for large-capacity memory systems where high speed, low power dissipation , and low costs are essential. The use of quadruple-layer polysilicon process combined with silicide technology and a single-transistor dynamic storage stacked capacitor cell provide high circuit density at reduced costs. Multiplexed address inputs permit both a reduction in pins and an increase in system densities. Self or extended refresh current is low enough for battery back-up application.

Note 2: Current flowing into IC is positive, out is negative. 3: ICC1 (AV), ICC3 (AV), ICC4 (AV) and ICC6 (AV) are dependent on cycle rate. Maximum current is measured at the fastest cycle rate. 4: ICC1 (AV) and ICC4 (AV) are dependent on output loading. Specified values are obtained with the output open. 5: Column Addres can be changed once or less while RAS=VIL and CAS=VIH.
