What is a RAM?
RAM stands for random access memory. It is a type of memory which is found in servers, desktops, smartphones, and printers etc. The data in RAM can be accessed randomly and you don’t need to traverse the previous data before reaching the desired one. It is a relatively faster memory because any piece of data can be accessed directly as compared to other memories which are accessed sequentially like a CD. However, It is a volatile memory which means if you switch off the device, the data in RAM will be erased.
It is also referred to as main memory, system memory or primary memory.
SAM, the opposite of RAM
The opposite of RAM is SAM and SAM stands for serial access memory. In the case of SAM, data is accessed sequentially just like in tape cassettes. All subsequent data is checked before reaching the desired data.
History of RAM
The first kind of RAM came into the market in 1947. It used CRT (Cathode Ray Tube) for storing its data. The second form of RAM also appeared in the market in 1947 and it used the magnetic core to store the data. However, solid state RAM was invented by Robert Dennard in 1968 and it used transistors to store the data.
Type of RAM
There are main types of RAM which are listed below.
- DRAM (Dynamic RAM)
- DRAM (static RAM)
1. Dynamic RAM
The word “dynamic” in DRAM indicates that this memory must be refreshed periodically otherwise it will lose its content.
2. Static RAM
Unlike DRAM, static RAM doesn’t need to be refreshed periodically and it is faster as compared with DRAM. It is used as computer’s cache memory.
Both DRAM and SRAM are volatile and they will lose their contents when a computer is powered off.
SRAM is further divided into the following type.
- NV-SRAM or Non-volatile SRAM – They have standard SRAM functionality but they retain the data when power is lost.
- PSRAM or Pseudo RAM – It works like a DRAM and has a self-refresh circuit.
Type of board and connector used for RAM
Earlier the board and connector used were proprietary. Later, two standards were evolved and they are listed below.
- SIMM or Single inline memory module
- DIMM or Dual inline memory module
1. SIMM or Single inline memory module
SIMM has a single line of the connector and it is now an obsolete standard.
2. DIMM or Dual inline memory module
DIMM meets today's growing speed and bandwidth capability and it is a dominant standard. The most popular type of DIMM is DDR, DDR2, and DDR3.
How much data RAM can store?
The highest capacity of RAM available in the market is 128 GB.
Manufacturer of RAM
Following are some of the manufacturer in the RAM technology market.
- Silicon Power
- Team Elite
- Team T-Force
How to find the amount of RAM installed on your computer?
To find the amount of RAM installed on your computer, follow these steps.
- Click the windows icon of your keyboard to open the start menu.
- Type “ram” from your keyboard. As soon as you type it, you will see “View RAM info”, click on it. A system dialog will appear where you can view the total size of installed RAM in your computer.
The above steps are applicable to both Windows 8 and Windows 10.
