The individual chips making up a 1 GB memory module are usually organized as 2 26 8-bit words, commonly expressed as 64M×8. Memory manufactured in this way is low-density RAM and is usually compatible with any motherboard specifying PC3200 DDR-400 memory. [18] [citation needed]
PC2-5300 DDR2 SO-DIMM (for notebooks) Comparison of memory modules for desktop PCs (DIMM) Comparison of memory modules for portable/mobile PCs (SO-DIMM) The key difference between DDR2 and DDR SDRAM is the increase in prefetch length. In DDR SDRAM, the prefetch length was two bits for every bit in a word; whereas it is four bits in DDR2 SDRAM.
The first commercial DDR SDRAM (double data rate SDRAM) memory chip was Samsung's 64 Mbit DDR SDRAM chip, released in June 1998. [30] GDDR (graphics DDR) is a form of DDR SGRAM (synchronous graphics RAM), which was first released by Samsung as a 16 Mbit memory chip in 1998. [31]
The first DDR4 memory module prototype was manufactured by Samsung and announced in January 2011. [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.
The nomenclature differs across memory technologies, but for commodity DDR SDRAM, DDR2 SDRAM, and DDR3 SDRAM memory, the total bandwidth is the product of: Base DRAM clock frequency; Number of data transfers per clock: Two, in the case of "double data rate" (DDR, DDR2, DDR3, DDR4) 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. [ 3 ] [ 4 ] In 1998, Samsung released a double data rate SDRAM, known as DDR SDRAM , chip (64 Mbit ) followed soon after by Hyundai Electronics (now SK Hynix ) the same year and ...
