Computers are a complex piece of equipment and we can’t usually gauge its capabilities and processes. A computer processes large amounts of information at a lightning-fast speed. With the upgraded memory module, desktop memory can be bigger, faster, and more powerful.

The memory module is an alternative name for the computer memory RAM chip. It is also used as a collective term to describe SIMM, DIMM, and SO-DIMM memory modules. Although there are various types of memory modules, they all serve the same function of storing data temporarily while the machine is running.

Memory modules are available in a range of sizes and have different pin configurations. For example, the original SIMM had 30 pins, which include metal contacts connecting to the motherboard. The new SIMM chip, however, has 72 pins. DIMMs are commonly available in 168-pin configurations, but some DIMMs have up to 240 pins. SO-DIMMs have a smaller shape factor than normal DIMM chips and are available in 72-pin, 144-pin, and 200-pin configurations.

Types Of Computer Memory Module

SIMM (Single In-Line Memory Module)

SIMMs originated with the 286, 386, and 486 computers and are typically memory modules that attach to the CPU motherboard (or memory extension).

SIMM can comprise of BEDO (Dynamic Random Access Memory), DRAM (Dynamic Random Access Memory), or EDO (Extended Dynamic Random Access Memory) with memory chips attached to a printed circuit board.

SIMMs are attached to the motherboard or memory expansion card to expand the memory capabilities of the computer. When you add memory to a computer, it usually comes in the form of a SIMM. The initial SIMMs each process 8 bits of data in a 30 pin configuration. Today, when the CPU can process 32 bits, the newer generation SIMMs are built with a 72-pin configuration.

DIMM (Dual In-Line Memory Module)

DIMMs have two rows of DRAM, BEDO, or EDO memory chips. With DIMMS, the memory of the same circuit board can be doubled. A typical DIMM is designed in a 168-pin configuration and processes 64-bit data simultaneously.

SODIMM (Small Outline Dual In-memory Memory Module)

SODIMMs are usually found in laptops and are smaller than standard DIMMs.

There are generally two types of SODIMMs:

First, which processes 32 bits of data simultaneously with a 72-pin configuration
Second, which processes 64-bit data with a 144-pin configuration.

RIMM (Rambus Inline Memory Module)

Rambus Inc., in coordination with Intel, is developing a new memory technology called Direct RDRAM with an embedded module known as RIMM. RIMM has a 184-pin configuration and offers a maximum transfer rate of 1.6 gigabytes per second (in the 16-bit data segment).

SORIMM (Small Outline Rambus Inline Memory Module)

SORIMM has a loop similar to SODIMM, but uses Rambus memory technology.

Different Types Of Memory Chips

DDR SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory)

This is an integrated memory circuit that allows transactions on the rising and falling edges of the clock cycle with a bus clock speed of 100 MHz at a data transfer rate of 200 MHz. DDR SDRAM is one of the best RAM modules for sale.

DRAM (Dynamic Random Access Memory)

DRAM is the most common type of computer memory. DRAM stores data for a relatively short period of time and must be updated regularly. DRAM is measured in terms of access time (in nanoseconds or ns) and storage capacity (in megabytes or MB).

EDO Memory (Extended Data Out)

EDO Memory is more efficient than DRAM with a performance increase of about 10-15% compared to DRAM.

BEDO Memory (Burst Extended Data Out)

BEDO memory is a more efficient memory than EDO with a performance increase of about 13% compared to EDO.

SDRAM (Static Dynamic Random Access Memory)

A memory chip that stores memory and does not need updating, SDRAM synchronizes with CPU time. While it's faster than DRAM, it's also more expensive. SDRAM is available at speeds from 66 to 266 MHz.

Other Types Of Memory

Random Access Video Memory (VRAM)

VRAM is the video version of the Fast Page Memory module and is mainly used in video accelerator cards.

Flash Memory

These are non-volatile memory chips that can be overwritten and act as a combination of random access memory and hard disk drive. If the power fails, data is stored in the flash memory. The advantages of flash memory include low voltage, durability, and high speed. This is why flash memory is primarily used in printers, pagers, digital cameras, audio recorders, and cell phones.

Shadow RAM

When the computer boots up, a minimum number of instructions to turn on the computer and videos are stored in ROM (read-only memory) called BIOS (basic input output system). Since ROM usually runs slow, Shadow RAM allows you to transfer selected segments of BIOS code from ROM to RAM which results in a faster transfer of data.

Conclusion

Upgrades to PC memory are fairly easy. Simply swap the memory module with a higher processing speed, or you can stack the chips and the motherboards as well. This allows you to use one slot and still create more memory for your machine to use.

You can buy these chips from the best eCommerce marketplaces or a hardware store where you can update your computer for a small fee. This can save you time and effort, particularly if you're not very computer-savvy.
