    Abstract: Apparatuses and methods for threshold voltage (Vt) distribution determination are described. A number of apparatuses can include sense circuitry configured to determine a first current on a source line of an array of memory cells, the first current corresponding to a first quantity of memory cells of a group of memory cells that conducts in response to a first sensing voltage applied to an access line and determine a second current on the source line, the second current corresponding to a second quantity of memory cells of the group that conducts in response to a second sensing voltage applied to the access line. The number of apparatuses can include a controller configured to determine at least a portion of a Vt distribution corresponding to the group of memory cells based, at least in part, on the first current and the second current.

    Abstract: This disclosure concerns memory cell sensing. One or more methods include determining a data state of a first memory cell coupled to a first data line, determining a data state of a third memory cell coupled to a third data line, transferring determined data of at least one of the first and the third memory cells to a data line control unit corresponding to a second data line to which a second memory cell is coupled, the second data line being adjacent to the first data line and the third data line, and determining a data state of the second memory cell based, at least partially, on the transferred determined data.

    Abstract: Memory devices, methods for programming sense flags, methods for sensing flags, and memory systems are disclosed. In one such memory device, the odd bit lines of a flag memory cell array are connected with a short circuit to a dynamic data cache. The even bit lines of the flag memory cell array are disconnected from the dynamic data cache. When an even page of a main memory cell array is read, the odd flag memory cells, comprising flag data, are read at the same time so that it can be determined whether the odd page of the main memory cell array has been programmed. If the flag data indicates that the odd page has not been programmed, threshold voltage windows can be adjusted to determine the states of the sensed even memory cell page.

    Abstract: Systems, methods, and apparatus related to a multi-level error correction architecture used for copying data in memory devices. In one approach, user data is stored in the first partition of a non-volatile memory. First error correction code data is generated for the user data and stored with the user data in the first partition. Second error correction code data is generated for the user data and stored outside the first partition. The second error correction code data provides an increased error correcting capability that is compatible with the error correction algorithm used with the first error correction code data. A copyback operation is used to copy the user data and the first error correction code, but not the second error correction code, to a second partition of the non-volatile memory. The second error correction code can be selectively used if there is a need to recover portions of the user data stored in the first partition.
