The memory of a computer contain of number of memory modules. Each module consists of an array of memory IC devices and an interface. Each IC device consists of an array of memory cells as shown in given fig. Each cell may store 1 bit.

Microprocessor do communicates with memory through memory interface.The primary function of memory interface is that the microprocessor might be able to write or from read to a given register of memory chip. The microprocessor might be able to choose the memory chip, send control signals for write or read operation. Certain signals to denote whether a Memory write or read operation has to be performed. Whenever a communication with memory is needed, a set of signals has to be sent by CPU.

Chip choose logic which is utilized to choose the specific chip based on the signal it receives from the transceiver.
