Abstract
A memory device includes logic to detect the last page written in multi-plane non-volatile memory. The device includes a memory array, and a storage controller. The memory array includes multiple planes and multiple word lines operable on the memory array. The storage controller is configured to divide the word lines into contiguous sub-ranges and assign a subset of the word lines to boundaries of the sub-ranges. Each word line of the subset of word lines is assigned to a page in a different one of the memory planes. The controller operates the subset of word lines to sense a page programmed or erased state from each of the memory planes in parallel.
