    摘要: 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.

    摘要: Embodiments of the invention describe methods, systems and apparatuses to improve solid state device (SSD) write speed by efficiently utilizing error correction code executed for the device. SSDs may be comprised of several NAND memory devices. It is understood that such devices tend to have a raw bit error rate (RBER) that is related to the program/erase cycle count for the device.Embodiments of the invention efficiently use system ECC by changing the operating conditions of the SSD to better utilize the robustness of the implemented ECC algorithm. For example, embodiments of the invention may alter the programming voltage supplied to an SSD to increase write speed; such an increase may increase the RBER of the device, but will not affect the accuracy of such operations due to the ECC that is provisioned for end of life storage fidelity (i.e., the RBER that will occur at the end of life).

    摘要: An apparatus and method for pre-charging an intermediate node for high-speed wordlines for accessing memory cells in high-speed memory arrays. The apparatus pre-charges a local capacitance located between a wordline supply voltage and the wordline to a voltage level that is greater than the wordline supply voltage. Once the wordline is selected, the charge stored on the local capacitance may be quickly shared with the capacitance of the wordline. The wordline supply voltage may be applied to the local capacitance to provide small, incremental voltage to move the wordline to its final voltage thereby improving the response time of the system.
