2. Internal RAM - Wikipedia

   en.wikipedia.org/wiki/Internal_RAM

   Random Access Memory is memory storage that if found in electronic devices such as computers. It holds data while the computer is on so that it can be quickly accessed by the CPU or (Central Processing Unit). [3] Ram is different from regular storage units such as Hard Disks, Solid State Drives, and Solid State Hybrid Drives.

3. DDR4 SDRAM - Wikipedia

   en.wikipedia.org/wiki/DDR4_SDRAM

   DDR4 is not compatible with any earlier type of random-access memory (RAM) due to different signaling voltage and physical interface, besides other factors. DDR4 SDRAM was released to the public market in Q2 2014, focusing on ECC memory , [ 6 ] while the non-ECC DDR4 modules became available in Q3 2014, accompanying the launch of Haswell-E ...

4. RAM drive - Wikipedia

   en.wikipedia.org/wiki/RAM_drive

   The 128kB Atari 130XE (with DOS 2.5) and Commodore 128 natively support RAM drives, as does ProDOS for the Apple II. On systems with 128kB or more of RAM, ProDOS automatically creates a RAM drive named /RAM. IBM added a RAM drive named VDISK.SYS to PC DOS (version 3.0) in August 1984, which was the first DOS component to use extended memory.

5. DDR SDRAM - Wikipedia

   en.wikipedia.org/wiki/DDR_SDRAM

   JEDEC has set standards for the data rates of DDR SDRAM, divided into two parts. The first specification is for memory chips, and the second is for memory modules. The first retail PC motherboard using DDR SDRAM was released in August 2000. [10]

6. Registered memory - Wikipedia

   en.wikipedia.org/wiki/Registered_memory

   Registered memory (also called buffered memory) is computer memory that has a register between the DRAM modules and the system's memory controller. A registered memory module places less electrical load on a memory controller than an unregistered one.

7. Trim (computing) - Wikipedia

   en.wikipedia.org/wiki/Trim_(computing)

   Regardless of operating system, the drive can detect when the computer writes all zeros to a block, and de-allocate (trim) that block instead of recording the block of zeros. If reading a de-allocated block always returns zeros, this shortcut is transparent to the user, except for faster writing (and reading) of all-zero blocks, in addition to ...
