Know About Memory Modules:
Memory modules are a broad term for RAM chips. It specifically refers to dynamic random access
memory integrated circuits modules mounted on a printed circuit board. There are different types of
memory but their main function is essentially the same, to put it in grossly simply terms. The term
modules are used to describe SIMM, DIMM and SO-DIMM memory. What distinguishes the different
types of memory are the voltage, capacity, speed, the form factor and the different pin configurations the
rams have. Memory-module is mainly used in personal computers, workstations, and servers. The
different types of memory are dual-in line package memory, TransFlash Modules, SIPP memory, SIMM,
and DIMM. DIMM, or dual in-line module, is used to refer to Rambus memory (RIMMS) or SO-DIMM
(smaller version of DIMM).
The memory modules that are used in desktop computers have become more advanced as technology has
improved dramatically. The first memory boards were not interchangeable with other product lines and
were only good for use in specific systems. SIMM, or single in-line module, was the first advancement in
technology that allowed memory to become more or less interchangeable. They utilized a 30-pin
connector design and were installed in parallel. SIMM boards, which came later, utilized a 72-pin design,
were slightly larger, and were capable of holding up to 256 MB of RAM. The subsequent advancement in
memory technology unveiled the DIMM, dual in-line memory-module, which boasted a 168-pin or 184-
pin connector with a range of 8 MB to 1 GB. DIMM coincided with the increased speed and bandwidth
capacity of the newer processors. SODIMM (small outline dual in-line memory module) is also made by
a handful of manufacturers. It has a range of 16 MB to 1 GB per module and is utilized in brands of
notebook computers such as Apple in order to conserve space. Memory today is much more reliable than
earlier models from the past. They have built-in error-checking, known as parity, to check for any errors
that may arise.
The following are considered major manufacturers of memory module:
Maxim Integrated, Micron Technology Inc, Omron Automation and Safety, Phoenix Contact, Qimonda,
SanDisk, Swissbit NA Inc, Terasic Technologies Inc, Wintec Industries, and Xilinx. In terms of just
desktop computer memory in general, the following are considered to be top manufacturers: Mushkin,
Corsair, G.Skill, Adata, Geil, Super Talent, Crucial, Kingston, Patriot, Transcend, and CellShock. Some
of these manufacturers have an overlap in terms of memory products as they offer a comprehensive
product line.
