A memory device includes: a memory cell array; a first latch; a second latch; a first circuit; and a second circuit. The memory cell array includes first, second, and third columns associated with first, second, and third addresses, respectively. The first latch stores the first address and is associated with a fourth address. The second latch stores the second address and is associated with a fifth address. The fourth address and the fifth address are in an ascending order. The first circuit selects the third column in place of the first column based on the first address.

Apparatuses and techniques are described for programming memory cells with a reduced number of program pulses. A program operation includes a first, foggy program pass followed by a second, fine program pass. The number of program loops in the foggy program pass is minimized while providing relatively narrow Vth distributions for the foggy states. The program loops include one or more checkpoint program loops in which a program speed of the memory cells is determined through a read operation. In a next program loop, the fast-programming memory cells are inhibited from programming while the slow-programming memory cells are programmed with a reduced speed by applying a program speed-reducing bit line voltage. This brings the threshold voltage of the slow-programming memory cells into alignment with the threshold voltage of the fast-programming memory cells.

A memory component includes a memory core comprising dynamic random access memory (DRAM) storage cells and a first circuit to receive external commands. The external commands include a read command that specifies transmitting data accessed from the memory core.

During the calibration, a selected one of the first data pattern and the second data pattern is transmitted by the second circuit onto the external bus in response to a read command received during the calibration. Further, at least one of the first and second data patterns is written to the pattern register circuitry in response to a write command received during the calibration.

The integrated circuit may include second latch circuitry having a single second latch that receives the latched multiple input data signals from the multiple first latches and outputs a single latched data signal based on the latched multiple input data signals. The integrated circuit may include intermediate logic circuitry that is coupled between the first latch circuitry and the second latch circuitry. The intermediate logic circuitry may receive and combine the multiple input data signals from the first latch circuitry into a single data signal that is provided to the single second latch of the second latch circuitry for output as the single latched data signal.

A page buffer includes a charging circuit, first and second storage circuits, and a selection circuit. The charging circuit charges a bit line during a precharging period. The first storage circuit determines and stores data corresponding to a state of a selected memory cell among memory cells connected to the bit line while the charging circuit charges the bit line. The second storage circuit, which is a circuit separate from the first storage circuit, determines and stores data corresponding to a state of the selected memory cell after the precharging period. The selection circuit outputs a control voltage controlling a switch element connected between the bit line and the charging circuit, and determines a magnitude of the control voltage during the precharging period, based on the data stored in the first storage circuit.
