Most users will only need about 8 GB of RAM, but if you want to use several apps at once, you might need 16 GB or more.
[a] Physical comparison of DDR, DDR2, DDR3, and DDR4 SDRAM Front and back of 8 GB [1] DDR4 memory modules. 2005: Standards body JEDEC began working on a successor to DDR3 around 2005, [14] about 2 years before the launch of DDR3 in 2007. [15] [16] The high-level architecture of DDR4 was planned for completion in 2008. [17]
The maximum random access memory (RAM) installed in any computer system is limited by hardware, software and economic factors. The hardware may have a limited number of address bus bits, limited by the processor package or design of the system. Some of the address space may be shared between RAM, peripherals, and read-only memory.
In the late 1980s IBM invented DDR SDRAM, they built a dual-edge clocking RAM and presented their results at the International Solid-State Circuits Convention in 1990. [ 6 ] [ 7 ] Samsung released the first commercial DDR SDRAM chip (64 Mbit ) in June 1998, [ 3 ] followed soon after by Hyundai Electronics (now SK Hynix ) the same year. [ 8 ]

In the fields of digital electronics and computer hardware, multi-channel memory architecture is a technology that increases the data transfer rate between the DRAM memory and the memory controller by adding more channels of communication between them. Theoretically, this multiplies the data rate by exactly the number of channels present.
At Hot Chips 2016, Samsung announced GDDR6 as the successor of GDDR5X. [5] [6] Samsung later announced that the first products would be 16 Gbit/s, 1.35 V chips.[7] [8] In January 2018, Samsung began mass production of 16 Gb (2 GB) GDDR6 chips, fabricated on a 10 nm class process and with a data rate of up to 18 Gbit/s per pin.
