    摘要: An apparatus and a method for adjusting signal timing in a memory interface have been disclosed. One embodiment of the apparatus includes a number of slave delay lock loops (DLLs) in a memory interface to adjust timing between a number of signals to compensate for timing skew, and a number of input/output (I/O) buffers to output the adjusted signals to one or more memory devices coupled to the memory interface. Other embodiments are described and claimed.

    摘要: An integrated circuit designed to be coupled to a suspendable memory, the integrated circuit comprising a memory enable deassertion delay (MEDD) logic setting a wait period for the deassertion of a memory enable signal after completion of a memory operation. The wait period is chosen for a preferred latency versus power savings tradeoff.

    摘要: An apparatus and method for correcting corrupted data. Access logic accesses a memory. Error detection logic generates an error signal for each data value output by the memory to indicate whether the data value has a correctable error. Correction logic requests the access logic to write to the memory a corrected version of each data value indicated by the error signal to have a correctable error.

    摘要: A method and apparatus for selective automatic precharge of dynamic random access memory banks is disclosed. By automatically precharging memory banks under certain conditions overall memory throughput can be improved because precharging is performed on a more selective basis. In one embodiment, the present invention provides support for multiple open banks of memory within a single memory sub-system. When multiple banks of memory are open simultaneously, a bank of memory that is less likely to be accessed in the future can be precharged when a new bank of memory is to be opened to service a memory request.

    摘要: An embodiment of the present invention is a technique to integrate data for a source synchronous protocol. A delay generator generates at least an integrating strobe from a data strobe synchronizing a data having a data window using the source synchronous protocol. A pulse generator generates a pulse from the at least integrating strobe. An integrating receiver integrates the data over an integration window defined by the pulse. The integration window is within the data window.
