Abstract
Apparatuses and techniques are described for reducing the number of latches used in sense circuits for a memory device. The number of internal user data latches in a sense circuit is reduced by using an external data transfer latch to store a bit of user data, in place of an internal user data latch. The user data in the data transfer latches identifies a subset of the data states which are not prohibited from having a verify test. The subset is shifted as the program operation proceeds, at specified program loops, to encompass higher data states. The completion of programming by a memory cell is indicated by the user data latches and another internal latch of the sense circuit in place of the external data transfer latch.
