    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.

  3. DDR SDRAM - Wikipedia

    Double Data Rate Synchronous Dynamic Random-Access Memory (DDR SDRAM) is a double data rate (DDR) synchronous dynamic random-access memory (SDRAM) class of memory integrated circuits used in computers.

  4. Double data rate - Wikipedia

    en.wikipedia.org/wiki/Double_data_rate

    Describing the bandwidth of a double-pumped bus can be confusing. Each clock edge is referred to as a beat, with two beats (one upbeat and one downbeat) per cycle.. Technically, the hertz is a unit of cycles per second, but many people refer to the number of transfers p

  5. Memory rank - Wikipedia

    en.wikipedia.org/wiki/Memory_rank

    A memory rank is a set of DRAM chips connected to the same chip select, which are therefore accessed simultaneously.In practice all DRAM chips share all of the other command and control signals, and only the chip select pins for each rank are separate (the data pins are shared across ranks).

  6. Memory timings - Wikipedia

    en.wikipedia.org/wiki/Memory_timings

    Memory timings or RAM timings describe the timing information of a memory module or the onboard LPDDRx. Due to the inherent qualities of VLSI and microelectronics, memory chips require time to fully execute commands.

    Eight Hyundai SDRAM ICs on a PC100 DIMM package. The earliest DRAMs were often synchronized with the CPU clock (clocked) and were used with early microprocessors. In the mid-1970s, DRAMs moved to the asynchronous design, but in the 1990s returned to synchronous operation.
