Read latency reduction in a memory device

A memory device can include: a memory array with memory cells arranged as data lines; an interface that receives a read command requesting bytes of data in a consecutively addressed order from an address of a starting byte; a first buffer that stores a first data line from the memory array that incl...

Zusammenfassung:A memory device can include: a memory array with memory cells arranged as data lines; an interface that receives a read command requesting bytes of data in a consecutively addressed order from an address of a starting byte; a first buffer that stores a first data line from the memory array that includes the starting byte; a second buffer that stores a second data line from the memory array, which is consecutively addressed with respect to the first data line; output circuitry configured to access data from the buffers, and to sequentially output each byte from the starting byte through a highest addressed byte of the first data line, and each byte from a lowest addressed byte of the second data line until the requested data bytes has been output; and a data strobe driver that clocks each byte of data output by a data strobe on the interface.
