DDR
Stands for "Double Data Rate." It is an advanced version of SDRAM, a type of computer memory. DDR-SDRAM, sometimes called "SDRAM II," can transfer data twice as fast as regular SDRAM chips. This is because DDR memory can send and receive signals twice per clock cycle. The efficient operation of DDR-SDRAM makes the memory great for notebook computers since it uses up less power.

What is ECC memory?
What is ECC memory?
For servers in businesses and data centers, it's mission-critical to minimize errors in data, and that's the purpose of ECC (Error Correcting Code) memory.
ECC is a method of detecting and then correcting single-bit memory errors. A single-bit memory error is a data error in server output or production, and the presence of errors can have a big impact on server performance.
There are two types of single-bit memory errors: hard errors and soft errors. Hard...

NVRAM – Non-Volatile Random Access Memory
NVRAM - Non-Volatile Random Access Memory
Abbreviation of Non-Volatile Random Access Memory, a type of memory that retains its contents when power is turned off. One type of NVRAM is SRAM that is made non-volatile by connecting it to a constant power source such as a battery. Another type of NVRAM uses EEPROMchips to save its contents when power is turned off. In this case, NVRAM is composed of a combination of SRAM and EEPROM chips.

RAM – random access memory
RAM - random access memory
RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessedrandomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers.
Main Types of RAM
DRAM (Dynamic Random Access Memory)
SRAM (Static Random Access Memory).
The two types of RAM differ in the technology they use to hold data,...
