Abstract:
A write block read apparatus for a memory device includes a dynamic read address decoder that receives static read address bits as inputs thereto and having an output used to implement a read operation of a memory location corresponding to the read address bits; a dynamic write address decoder that receives static write address bits as inputs thereto and having an output used to implement a write operation of a memory location corresponding to the write address bits; and a static write address decoder, configured in parallel with the dynamic write address decoder, the static write address decoder configured to receive a portion of the static write address bits as inputs thereto, and wherein the static write address decoder is coupled to the dynamic read address decoder so as to block the read operation upon an address conflict with the write operation.
