Title: Clocked memory device that includes a programming mechanism for setting write recovery time as a function of the input clock

Abstract: A clocked memory device includes a programming mechanism that allows the write recovery time during a command with auto precharge enabled to be dynamically set to some function of the input clock. In the preferred embodiments, the programming mechanism includes a control register with programmable bits that allows specifying the write recovery time according to the bit values written to the control register. For example, write recovery time could be specified as a whole or fractional number of clock cycles. By specifying the write recovery time as a function of the clock that may be dynamically set, the clocked memory device may be used at its highest performance capabilities over a wide range of operating frequencies.
