If it is organized as a 1024 x 1 memory chips, then it has got 1024 memory words of size 1 bit only.

Therefore, the size of data bus is 1 bit and the size of address bus is 10 bits ().

A particular memory location is identified by the contents of memory address bus. A decoder is used to decode the memory address. There are two ways of decoding of a memory address depending upon the organization of the memory module.

In one case, each memory word is organized in a row. In this case whole memory address bus is used together to decode the address of the specified location. The memory organization of 1024 x 1 memory chip is shown in the figure 3.7.
