RAM Chips & ROM Chips

RAM Chips and ROM Chips

Random Access Memory (RAM) is the short-term memory used to store information that is being processed. It is available as a RAM Chip, which is an integrated circuit (IC) Soldered on the motherboard. The two types of RAM are static RAM(SRAM) and dynamic RAM (DRAM). SRAM is expensive to produce, but faster and requires less dynamic power than DRAM. SRAM is typically used as a cache memory for the CPU.

The following figures Shows RAMs:

 Memory modules come in several form factors, such as:

• Single inline memory (SIMM)- SIMM has a single row of 30 or 72 edge connectors on the bottom of the module. Single refers to both sides of the module having the same pinout.
• Dual inline memory module(DIMM)- DIMM is available in 168-pin, 184-pin, and 240-pin versions. Dual refers to each side of the module having a different input.
• Small Outline DIMM(SODIMM)- SODIMM is a compact version of the standard DIMM module, available in various pinout for use in notebook computers and laser/LED printers.
• Rambus inline memory module (RIMM)

Read-only memory (ROM) is a non-volatile memory. It is available as a ROM chip, which is also an IC soldered on the motherboard. The five basic types of ROM are:

• ROM- Read-Only Memory
• PROM- Programmable Read-Only Memory
• EPROM- Erasable Programmable Read-Only Memory
• EEPROM- Electrically Erasable Programmable Read-Only Memory
• Flash EEPROM memory
