== Address decoder selects the storage cell in a memory ==
An address decoder is a commonly used component in microelectronics that is used to select memory cells in randomly addressable memory devices.
Such a memory cell consists of a fixed number of memory elements or bits . The address decoder is connected to an address bus and reads the address created there. Using a special switching logic, it uses this address to calculate which memory cell is to be accessed. It then selects that cell by selecting it via a special control line. This line is also known as the select line. In dynamic memories (DRAM) , there are row and column select lines on the memory matrix, which are controlled by address decoders integrated in the chip.
