What is a memory chip

A memory chip is an electronic part which is used by a computer, any type of computer, to store a program or data. The difference between a program and data is that a program is a sequence of instructions which tell the computer what to do. Data is information which the computer references as it runs it’s program. In the memory chip the program and data information appear to be identical as they are both stored as a series of 1’s and 0’s.

There are two basic types of memory chips. These are volatile and non-volatile. A volatile memory part will lose its contents (it forgets) when power is removed. A non-volatile memory chip will not lose its contents when power is removed. An EPROM is a non-volatile memory chip.
