    摘要： Technology for a memory device operable to program memory cells in the memory device is described. The memory device can include a plurality of memory cells and a memory controller. The memory controller can perform a first programming pass to program a memory cell in the plurality of memory cells. A defined number of blanket programming pulses can be applied to the memory cell during the first programming pass. The blanket programming pulses may not include verify operations. The memory controller can perform a second programming pass to program the memory cell. A defined number of program and verify (PV) pulses can be applied to the memory cell during the second programming pass.

    摘要： Technology for programming a page of memory in a NAND memory device is disclosed and described. In an example, a method may include applying initial programming pulses for lower page programming of the page and pre-reading data of the lower page. The method may further include determining whether to apply an error recovery operation to the data of the lower page. Data indicative of secondary programming pulses to be used for programming upper page data are stored and the upper page data is programmed based on the secondary programming pulses and the data of the lower page.

    摘要： Some embodiments include apparatus, systems, and methods that operate to apply a first value of a drain select gate voltage during a first portion of a programming time period associated with programming a plurality of memory cells, and to apply a second value of the drain select gate voltage different from the first value during a second, subsequent portion of the programming time period. The drain select gate voltage may be changed between groups of programming pulses in a single programming cycle. The first and second portions may be determined according to the number of applied programming pulses, the number of memory cells that have been completely programmed, and/or other conditions. Additional apparatus, systems, and methods are disclosed.
