ABSTRACT:
In some embodiments, a chip includes a memory core, error detection circuitry, and a control unit. The error detection circuitry determines the validity of error detection signals associated with speculative and non-speculative commands received by the chip and to provide validity signals indicative of the determined validity. The control unit provides the speculative commands to the memory core to be acted on before the control unit receives the associated validity signals and to provide the non-speculative commands to the memory core to be acted on only after receiving associated validity signals that indicate the associated error detection signals are valid. Other embodiments are described and claimed.
