摘要: A optical link for achieving electrical isolation between a controller and a memory device is disclosed. The optical link increases the noise immunity of electrical interconnections, and allows the memory device to be placed a greater distance from the processor than is conventional without power-consuming I/O buffers.

摘要: A differential clock receiver for a SynchLink-type Synchronous Dynamic Random Access Memory (SLDRAM) includes a differential amplifier with a novel method for biasing its NMOS and PMOS current sources. A differential clock received and amplified by the differential amplifier switches a set of multiplexers, which respond by outputting a differential output clock. The multiplexers can be "disabled" by an inactive enable signal so they output a constant "0" level for the differential output clock. This disabling feature of the differential clock recciver is particularly useful with the intermittent data clocks found in SLDRAMs. Also, the novel biasing method for the current sources of the differential amplifier gives the clock receiver very low skew.
