Abstract
An interface and method for a synchronous DRAM (syncDRAM) memory are provided that improve performance. The read operation in a syncDRAM is significantly sped up by eliminating the step of opening a new page of data in a SyncDRAM using a speculative read method. This provides the ability to open a page of information in the SyncDRAM with a command generator in response to a data request. Speculative read logic is also included to continue reading from the page with an invalid address until a second read request occurs. Thus, in the event that a subsequent read request occurs that requests data located on the same page as the prior request, the data can be indexed and read from a location on that page without having to first assert the SCS# and SCAS#. This frequently removes the step of opening a page from the read process and, over time, can significantly speed up the overall SyncDRAM reads in a computer system.
