The latest computer RAM for system memory is Double Data Rate 3 (DDR3). For graphics memory, the latest is Graphics Double Data Rate 5 (GDDR5).
it means DOUBLE DATA RAM WITH 1GB
Yes, although you won't here DDR1 used by anyone.
Full form of DDR is Double Data Rate. DDR-SDRAM : Double Data Rate Synchronous Dynamic Random Access Memory.
Yes they are definitely different as DDR stands for Double Data Ram & SDR stands for Single Data Ram and further explanation can be found here http://en.wikipedia.org/wiki/DDR_SDRAM
DDR stands for Double Data Rate, which means data travels at twice the clock rate. DDR is referring to RAM or Random Access Memory and the connector is the socket into which you install RAM.
DDR RAM (Double Data Rate RAM) Instead of processing data for each beat of the system clock, as regular SDRAM does, it processes data when the beat rises and again when it falls, doubling the data rate of memory. If a motherboard runs at 200 MHz, DDR memory runs at 400 MHz.
Double sided PC memory is a RAM module that posses two edges (a rising and a falling edge) on which data is received/sent. An example is DDR and DDR2 RAM.
DDR3 itself, stands for double data rate (revision 3). DDR3 commonly precedes "memory" or "RAM." DDR3 SDRAM is used in most modern computers or laptops, although DDR4 RAM will make its debut in the next year.
The "S" stands for Synchronous RAM. By Synchronous that means it worked with the system clock and the speed of the RAM is the same as the speed of the system bus. So if the system bus is operating at 100MHz then Synchronous RAM also operated at 100MHz. It has since been replaced by Double Data Rate RAM (DDR). Double Data Rate goes twice as fast as the system clock, it sends data on the upswing of the clock and again on the downcycle of the system clock so it can send data twice as fast as the Synchronous RAM which sent data once per clock cycle. Hope this helps.
It is SRAM (Static RAM) which means it does not have to be refreshed. DRAM (Dynamic RAM) has to be constantly refreshed in order to keep the data. DDR Double data rate reads and writes on the same up ie _ __ _| |___|_|__ on both ups (in this example 4 times)
Ddr stands for double data rate. Which actually doubles the speed compare to sd ram
