摘要: Methods for program verifying, program verify circuits, and memory devices are disclosed. One such method for program verifying includes generating a ramped voltage for a plurality of count values. The ramped voltage is applied to a control gate of a memory cell being program verified. At least a portion of each count value is compared to an indication of a target threshold voltage for the memory cell. When the at least a portion of the count value is equal to the indication of the target threshold voltage indication, sense circuitry is used to check if the memory cell has been activated by the voltage generated by the count. If the memory cell has been activated, an inhibit latch is set to inhibit further programming of the memory cell. If the memory cell has not been activated by the voltage, the memory cell is biased with another programming pulse.

摘要: A selected memory cell on a selected word line is programmed through a plurality of programming pulses that are incremented by a step voltage. After a successful program verify operation, programming of the selected memory cell is inhibited while other memory cells of the selected word line are being programmed. Another program verify operation is performed on the selected memory cell. If the program verify operation fails, a bit line coupled to the selected cell is biased at the step voltage and a final programming pulse is issued to the selected word line. The selected memory cell is then locked from further programming without evaluating the final program verify operation.

摘要: Methods for programming a memory device and memory devices are provided. According to at least one such method, a selected memory cell is programmed by a series of programming pulses. The series of programming pulses are configured in sets of programming pulses where each set has the same quantity of pulses and each programming pulse in the set has substantially the same amplitude (i.e., programming voltage). The amplitude of the programming pulses of subsequent sets is increased by a step voltage from the previous amplitude.

摘要: This disclosure concerns memory kink compensation. One method embodiment includes applying a number of sequentially incrementing programming pulses to a memory cell, with the sequential programming pulses incrementing by a first programming pulse step voltage magnitude. A seeding voltage is applied after applying the number of sequentially incrementing programming pulses. A next programming pulse is applied after applying the seeding voltage, with the next programming pulse being adjusted relative to a preceding one of the sequentially incrementing programming pulses by a second programming pulse step voltage magnitude. The second programming pulse step voltage magnitude can be less than the first programming pulse step voltage magnitude.

摘要: Memory devices and methods are disclosed to facilitate adjustment of program voltages applied during a program operation based upon erase operation cycle counter values stored in the memory device. In one such embodiment, an erase cycle counter is maintained for each block of a memory device and is stored in the associated block of memory. Programming voltage levels utilized during program operations of memory cells are determined, at least in part, based upon the value of the erase cycle counter stored in a memory block undergoing a programming operation, for example.

摘要: Embodiments of the present disclosure provide methods, devices, modules, and systems for programming multilevel non-volatile multilevel memory cells. One method includes increasing a threshold voltage (Vt) for each of a number of memory cells until the Vt reaches a verify voltage (VFY) corresponding to a program state among a number of program states. The method includes determining whether the Vt of each of the cells has reached a pre-verify voltage (PVFY) associated with the program state, selectively biasing bit lines coupled to those cells whose Vt has reached the PVFY, adjusting the PVFY to a different level, and selectively biasing bit lines coupled to cells whose Vt has reached the adjusted PVFY, wherein the PVFY and the adjusted PVFY are less than the VFY.
