PD2114L·5 DESCRIPTION 4098 BIT (1024 )( 4 BITS) STATIC RAM The NEC I.lPD2114L is a 4096 bit static Random Access Memory organized as 1024 words by 4 bits using N-channeISilicon-gate MOS technology_ It uses fully DC stable (static) circuitry throughout, in both the array and the decoding_ It therefore requires no clocks or refreshing to operate and simplifies system design. The data is read out nondestructively and has the same polarity as the input data_ Common input/output pins are provided. II The I.lPD2114L is designed for memory applications where high performance, low cost, large bit storage, and simple interfacing are important design objectives. The I.lPD2114L is placed in an 18-pin package for the highest possible density. It is directly TTL compatible in all respects: inputs, outputs, and a single +5V supply. A separate Chip Select (CS) lead allows easy selection of an individual packag...
