  • Publication number: 20240393977
    Abstract: A memory device includes a memory array configured as quad-level cell (QLC) memory and a control logic operatively coupled to the memory array. The control logic identifies a first two bits of particular pages of a QLC logical state. The control logic causes memory cells of the memory array to be coarse programmed with a threshold voltage distribution of a multi-level cell (MLC) logical state corresponding to the first two bits. The control logic reads the MLC logical state from the memory cells and a second two bits from a cache buffer to determine the QLC logical state. The control logic causes the memory cells to be further coarse programmed with a QLC threshold voltage distribution corresponding to the QLC logical state.

  • Publication number: 20240339158
    Abstract: Control logic in a memory device initiates a program operation including a first phase including applying a ramping voltage level to a set of wordlines of a memory device to boost a set of pillar voltages and a second phase including applying a set of programming pulses to a wordline associated with one or more memory cells of the memory device to be programmed to a set of programming levels, wherein each programming level of the set of programming levels is programmed by each programming pulse. During the first phase of the program operation, a first voltage applied to a drain-side select line (SGD) is adjusted from a first SGD voltage level to a second SGD voltage level.

  • Patent number: 8344367
    Abstract: Molecular devices and methods of manufacturing the molecular device are provided. The molecular device may include a lower electrode on a substrate and a self-assembled monolayer on the lower electrode. After an upper electrode is formed on the self-assembled monolayer, the self-assembled monolayer may be removed to form a gap between the lower electrode and the upper electrode. A functional molecule having a functional group may be injected into the gap.
