[9] [10] On November 15, 2018, SK Hynix announced completion of its first DDR5 RAM chip; running at 5.2 GT/s at 1.1 V. [11] In February 2019, SK Hynix announced a 6.4 GT/s chip, the highest speed specified by the preliminary DDR5 standard. [12] The first production DDR5 DRAM chip was officially launched by SK Hynix on October 6, 2020. [13] [14]
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 ]
[9] [10] Hynix 40 nm class "2 Gb" (2 × 1024 3 bit) GDDR5 was released in 2010. It operates at 7 GHz effective clock-speed and processes up to 28 GB/s. [11] [12] "2 Gb" GDDR5 memory chips will enable graphics cards with 2 GB or more of onboard memory with 224 GB/s or higher peak bandwidth.

Sleep has been shown to have a long list of physical and mental health benefits, and now a new study suggests it could also help to “erase" bad memories. Experts comment on the findings.
Alijah Martin scored 18 points, Denzel Aberdeen added 16 and No. 8 Florida thumped top-ranked Tennessee 73-43 on Tuesday night to knock off the last unbeaten team in Division I basketball. Alex ...
The command encoding is identical to LPDDR2, using a 10-bit double data rate CA bus. [7] However, the standard only specifies 8 n -prefetch DRAM, and does not include the flash memory commands. Products using LPDDR3 include the 2013 MacBook Air, iPhone 5S , iPhone 6 , Nexus 10 , Samsung Galaxy S4 (GT-I9500) and Microsoft Surface Pro 3 and 4. [ 10 ]
Solid-state hard drives have continued to increase in speed, from ~400 Mbit/s via SATA3 in 2012 up to ~7 GB/s via NVMe/PCIe in 2024, closing the gap between RAM and hard disk speeds, although RAM continues to be an order of magnitude faster, with single-lane DDR5 8000MHz capable of 128 GB/s, and modern GDDR even faster.
