Patent abstract

A memory device for reducing the number of data read lines needed in a memory device. Specifically, multiple helper flip-flops are used to prefetch data in a memory device. The helper flip-flops are configured to latch one or two of the data bits from a 4-bit prefetch in an alternating periodic fashion, thereby necessitating fewer data lines.
