Abstract
A memory device that dynamically adjusts the sense time to read an open block of a memory block is disclosed. The adjusted sense time is based upon various considerations, including the sense time of the closed block equivalent and the openness of the open block. This allows the memory device to maintain a fixed Vt as well as reduce failed bit count, i.e., read errors due to an insufficient sense time. Also, the dynamic adjustment of sense time can optimize system performance and increase efficiency.
