Memory - modules are solid-state data storage devices with standardized physical module formats that are computer chips used to add memory to a computer. Memory family products are similar to memory card modules used in computing equipment and devices that can accept standard memory modules. There are two fundamental distinctions between memory: volatile memory, where the data is lost as the power is removed, and non-volatile memory, which stores the data without power.
Types of memory – modules:
There are two types of modules in RAM: Single In-line Memory Module (SIMM) and Dual In-line Memory Module (DIMM).
- Single In-line Memory Module (SIMM):
A SIMM is a module comprised of one or several random-access memory (RAM) chips on a small circuit board with pins connected to the computer motherboard. The more RAM your computer has, the less frequently it will need to access your secondary storage, such as a hard disk or CD-ROM. Sometimes, PC owners expand RAM by installing additional SIMMs on their PCs.
- Dual In-line Memory Module (DIMM):
A DIMM is a small circuit board computer memory that uses a 64-bit memory bus to transfer data efficiently. Unlike a SIMM, a DIMM contains one or several random-access memory chips connected to the computer motherboard via pins. DIMMs store each data bit in a separate memory cell and adopt a 64-bit data path due to the use of processors in personal computers with 64-bit data width. DIMMs are primarily used in desktops, printers, laptops, and other related devices.
What is an SDRAM module?
An SDRAM (Synchronous Dynamic Random Access Memory) is a dynamic RAM chip that can divide the chip into two cell blocks and incorporate data between them. SDRAMs are best suited for computers and other computing-related technology.
What is SRAM?
Static Random Access Memory (SRAM or Static RAM) is a storage device that stores a bit of data on four transistors in a static form using two cross-coupled inverters. It holds the data as long as the memory has power and does not need to be refreshed.
Applications of Memory – Modules:
Memory modules are ideal for various digital electronic devices, from smartphones and watches to electronic toothbrushes and radios. Every electric device requires memory modules for storing information. For instance, for a monitor or TV, these modules function as internal software to run the device or as temporary storage for processors. They are widely used in:
- Refrigerators
- Thermostats
- Digital electronics
- Servers and networking
- Motherboards and RAID cards
- Printers and imaging
- Air conditioners
- Automobiles, and
- Personal computing.
