RANDOM ACCESS MEMORY(RAM)
What Does Random Access Memory (RAM) Mean?
Computer memory, often known as random access memory (RAM), is the short-term data storage of your system; it saves the information that your computer is actively using so that it may be accessed quickly. The more apps your computer runs, the more memory it will require.
Many of your computer’s routine functions, such as loading software, accessing the internet, updating a spreadsheet, or playing the latest game, rely on RAM. Memory also enables you to switch swiftly between various jobs, remembering where you were in the previous one when you go to the next. The more memory you have, on average, the better.
You’ve utilised memory in multiple ways when you switch on your computer and open a spreadsheet to change it, but first check your email.
Memory is used to load and operate programmes, such as your spreadsheet programme, respond to commands, such as any spreadsheet adjustments you made, and toggle between several programmes, such as when you left the spreadsheet to check email.
Your computer is almost constantly actively using memory.
The three main memory circuit boards types containing chips are:
- RIMMs (Rambus in-line memory modules).
- SIMMs (single in-line memory modules).
- DIMMs (dual in-line memory modules).
Most motherboards today use DIMMs.
Dynamic random access memory (DRAM), sometimes known as Dynamic RAM, and Static random access memory (SRAM) are the two major forms of RAM (SRAM). Dynamic RAM is used in the majority of personal computers (PCs). Every few milliseconds, all dynamic RAM chips on DIMMs, SIMMs, and RIMMs must refresh by rewriting data to the module.
chips on DIMMs, SIMMs, and RIMMs must refresh by rewriting data to the module.
Static RAM (SRAM) is a type of volatile memory that is commonly used in cache memory and registers since it is much faster than dynamic RAM and does not require refreshing. SRAM preserves its material as long as power is supplied, thus there’s no need to refresh it on a regular basis.
SRAM employs a 6-transistor matrix that does not rely on electricity to prevent leakages, as they act as switches that serve as 1s and 0s with no capacitor to maintain the charge. However, because the matrix requires more transistors than a DRAM, it takes up more space, resulting in greater production costs.
Memory that needs to be refreshed is referred to as dynamic RAM. The memory controller, which is part of the motherboard’s chipset, performs the refreshing. Each cell is contained within an electrical capacitor, with transistors acting as gates to determine whether each value may be read or written.
To compensate for the capacitor’s leaks, the DRAM must be refreshed every few milliseconds with an electrical charge that rewrites the data. DRAMs are smaller and less expensive than SRAMs and are found in almost every computer.
