SyncLink SDRAM, along with Direct Rambus DRAM, is a protocol -based approach where all signals to random access memory ( RAM ) are on the same line (rather than having separate column address strobe , row address strobe , address, and data lines). Since access time does not depend on synchronizing operations on multiple lines, SLDRAM promises RAM speed of up to 800 MHz. Like Double Data Rate SDRAM, SLDRAM can operate at twice the system clock rate. SyncLink is an open industry standard that is expected to compete with Direct Rambus DRAM.
