WebDec 5, 2024 · The 2-bit address will be input as a 2 x 4 decoder, this decoder will have 4 output and the input will have 2 bits. The 4 output of the decoder will enable every RAM of 128 x 8 individually. Also, we can write 128 x 8 RAM chip as 2 7 x 8, every RAM chip will need a 7-bit address. We will connect the remaining 7-bit address line to every RAM.

I tried the … WebApr 1, 2024 · SRAM image. SRAM is a type of semiconductor memory that uses Bistable latching circuitry to store each bit. In this type of RAM, data is stored using the six transistor memory cell. Static RAM is mostly used as a cache memory for the processor (CPU). SRAM is relatively faster than other RAM types, such as DRAM. It also consumes less power.
