Memory must be compatible with the other components in a computer system. Each successive generation is faster and uses less energy. Memory standards are controlled by JEDEC, the Joint Electron Device Engineering Council, an independent semiconductor engineering trade organization and standardization body. The next generation of memory, DDR2, is faster and uses less energy than the original DDR. Using both beats to transfer data makes double data rate memory significantly faster than single data-rate memory, which used only one edge of the clock signal to transfer data. Double data-rate is different than dual-channel memory, learn about dual-channel memory here. A clock signal is made up of both a downbeat and an upbeat. DDR was both faster and used less energy than SDR. DDR memory transfers data to the processor on both the rising and falling edges of the clock signal. Double data rate, or DDR, was developed, and the previous technology became known as single data rate, or SDR. Synchronous memory synchronizes the memory module's responses with the system bus.Īs other computer components increased their speed, memory speed also needed to increase. Previously, memory had to be asynchronous, that is, it operated independently of the processor. SDRAM (synchronous dynamic random access memory) was developed in response to increased speed in other computer components.
