Memory cell :-

• The memory cell is the fundamental building block of computer memory. It is the smallest part of a computer memory that can be changed in a single operation. The memory cell is an electronic circuit that stores one bit of binary information and it must be set to store a logic 1 (high voltage level) and reset to store a logic 0 (low voltage level). A memory cell has an identification number called its address. The value in the memory cell can be accessed by reading it.

• Over the history of computing many different memories cell architectures have been used including core memory and bubble memory, but the most common ones used for random access memory (RAM) are flip-flops (using MOSFET transistors) and capacitors.

• The SRAM (static RAM) memory cell is a type of flip-flop circuit, usually implemented using MOSFETs (metal-oxide-semiconductor field effect transistors). These require very low power to keep the stored value when not being accessed. A second type, DRAM (dynamic RAM), is based around a capacitor can store a ‘1’ or ‘0’ in the cell. However, the charge in this capacitor will slowly leak away, and must be refreshed periodically. Because of this refresh process, DRAM uses more power, but can achieve greater storage densities.

• On the other hand, most non-volatile memory (NVM) are based on floating-gate memory cell architecture. Non-volatile memory technologies including EPROM, EEPROM and flash memory use floating-gate memory cells, which are base around floating-gate MOSFET transistors.
