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.
There are two types of modules in RAM: Single In-line Memory Module (SIMM) and Dual In-line Memory Module (DIMM).
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.
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.
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.
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.
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:
