Memories are made up of registers. Each register in the memory is one storage location. Storage location is also called as memory location. Memory locations are identified using Address. The total number of bit a memory can store is its capacity.
A storage element is called a Cell. Each register is made up of storage element in which one bit of data is stored. The data in a memory are stored and retrieved by the process called writing and reading respectively.
A word is a group of bits where a memory unit stores binary information. A word with group of 8 bits is called a byte.
A memory unit consists of data lines, address selection lines, and control lines that specify the direction of transfer. The block diagram of a memory unit is shown below:
Data lines provide the information to be stored in memory. The control inputs specify the direction transfer. The k-address lines specify the word chosen.
When there are k address lines, 2k memory word can be accessed.
