A circuit which can store information is known as Memory cell.
But memory is a key element of digital systems. In computers, it allows to store both programs and data and memory cells are also used for temporary storage of the output of combinational circuits to be used later by digital systems. Logic circuits that use memory cells are called sequential circuits.
A memory cell is the smallest part of a computer memory that can be changed in a single operation. A memory cell records a number written in binary - called its content.
