UPD2114L-1 4K-Bit Static RAM

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.
