Study Notes
Overview of Memory Devices and Their Types
- RAM and ROM are two primary types of semiconductor memories.
- RAM is volatile, and the data is lost when the power source is removed, but non-volatile RAMs exist.
- ROM is non-volatile, and the logic function is stored permanently without electrical power.
- EPROM or Erasable PROM can be erased and reused by shining ultraviolet light on to the chip.
- PROM or Programmable ROM is not stored during manufacture, but later in the field by a user with necessary programming equipment.
- EEPROM or E2PROM is a special type of erasable semiconductor memory where the data can be erased and re-written electrically in circuit.
- Flash memory is a type of EEPROM that updates its contents in terms of groups of bytes or sectors.
- NAND flash memory is commonly available as “memory cards” like Compact Flash (CF), Secure Digital (SD), MultiMedia Card (MMC) formats, etc.
- RAM devices can be classified into two types: static and dynamic.
- Static RAM's use a flip-flop as the storage element, and information is retained in the F/F for as long as power is applied.
- Dynamic RAMs use the ability of MOS capacitors to store charge as the basic storage element, which must be refreshed regularly.
- RAMs are manufactured using both MOS and bipolar technologies.
