Design of Memory :

A memory unit is a collection of storage cells together with associated circuits needed to transform insformation in and out of the device. Memory cells which can be accessed for information transfer to or from any desired random location is called random access memory(RAM). The block diagram of a memory unit-

Internal Construction: The internal construction of a random-access memory of m words with n bits per word consists of m*n binary storage cells and associated decoding circuits for selecting individual words. The binary cell is the basic building block of a memory unit.

RAM Design:

Design of a RAM Cell

Design of a 4X4 RAM

Design Issues :

A basic RAM cell has been provided here as a component which can be used to design larger memory units. An IC memory consisting of 4 words each having 3 bits has been aslo provided.
