What is SDRAM?
| Synchronous DRAM |
|
A DRAM technology that uses a clock to synchronize signal input and output on a memory chip. The clock is coordinated with the CPU clock so the timing of the memory chips and the timing of the CPU are "in synch." The synchronization eliminates time delays and allows for fast consecutive read and write capability, thereby increasing the overall performance of the computer. SDRAM has two separate memory banks that operate simultaneously, while one bank prepares for access, the other is being accessed. SDRAM allows the CPU to access memory approximately 25 percent faster than EDO memory because it is controlled by the system clock. SDRAMs can only be used in computers designed for it and cannot be mixed with any other type of memory. SDRAM can operate at 100MHz, 133Mhz and features a burst mode that allows it to address blocks of information instead of small data bits. |
