Abstract: An apparatus and method for providing high throughput memory responses are provided. The apparatus includes a memory device including a plurality of memory arrays, a memory controller configured to control the memory device, the memory controller having a read queue, a write queue, and an address match circuit, and a data output circuit. The memory controller receives a read request, searches the write queue for a write address that matches a read address of the read request, and sends data associated with the write address from the write queue to the data output circuit without accessing the memory device when the write address matches the read address, the write address that matches the read address being a target address. The data output circuit outputs the data associated with the target address to an external device.
