摘要: Low supply voltage memory apparatuses are presented. In one embodiment, a memory apparatus comprises a memory and a memory controller. The memory controller includes a read controller. The read controller prevents a read operation to a memory location from being completed, for at least N clock cycles after a write operation to the memory location, where N is the number of clock cycles for the memory location to stabilize after the write operation.

摘要: Methods and apparatuses for on-line testing for decode logic are presented. In one embodiment, a processor comprises translation logic to decode an instruction to micro-operations and extraction logic to determine first information about numbers of occurrences of fields in the micro-operations. In one embodiment, the processor further comprises verification logic to indicate whether the decoding results of the instruction are accurate based at least on the first information.
