Double Data Rate 5 Synchronous Dynamic Random-Access Memory (DDR5 SDRAM) is a type of synchronous dynamic random-access memory. Compared to its predecessor DDR4 SDRAM, DDR5 was planned to reduce power consumption, while doubling bandwidth. [5] The standard, originally targeted for 2018, [6] was released on July 14, 2020. [2]
DDR SDRAM specification was finalized by JEDEC in June 2000 (JESD79). [9] 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]
Typical SDR SDRAM clock rates are 66, 100, and 133 MHz (periods of 15, 10, and 7.5 ns), respectively denoted PC66, PC100, and PC133. Clock rates up to 200 MHz were available. It operates at a voltage of 3.3 V. This type of SDRAM is slower than the DDR variants, because only one word of data is transmitted per clock cycle (single data rate).
288-pin: DDR4 SDRAM and DDR5 SDRAM [7] SO-DIMM. 72-pin: FPM DRAM and EDO DRAM; [8] different pin configuration from 72-pin SIMM; 144-pin: SDR SDRAM, [8] sometimes used for DDR2 SDRAM; 200-pin: DDR SDRAM [8] and DDR2 SDRAM; 204-pin: DDR3 SDRAM; 260-pin: DDR4 SDRAM; 260-pin: UniDIMMs carrying either DDR3 or DDR4 SDRAM; differently notched than ...
In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module.Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.
Graphics Double Data Rate 5 Synchronous Dynamic Random-Access Memory (GDDR5 SDRAM) is a type of synchronous graphics random-access memory (SGRAM) with a high bandwidth ("double data rate") interface designed for use in graphics cards, game consoles, and high-performance computing. [1] It is a type of GDDR SDRAM (graphics DDR SDRAM).

In April 2022, Dell launched laptops in the Dell Precision 7000-series that used a custom form factor of CAMM for DDR5 SDRAM. [ 8 ] In June 2023, ADATA demoed an updated design CAMM memory module, [ 9 ] which looks different (and more compact) than Dell's 2022 design.
