摘要： A system and method, including computer software, allows reading data from a flash memory cell. Voltages from a group of memory cells are detected. The group of memory cells have associated metadata for error detection, and each memory cell stores a voltage representing a data value selected from multiple possible data values. Each possible data value corresponds to one range of multiple non-overlapping ranges of analog voltages. Memory cells having uncertain data values are identified based on the detected voltages. Alternative data values for the memory cells having the uncertain data values are determined, and a combination of alternative data values is selected. An error detection test is performed using the metadata associated with the multiple memory cells and the selected combination of alternative data values.

摘要： Systems and methods, including computer software for performing operations enable interleaving of charging operations in a charging pump. A first charge pump is charged to a predetermined level, and a first operation is performed using a charge stored in the first charge pump after it reaches the predetermined level. A second charge pump is charged during a time that overlaps with performing the first operation. A second operation is performed using a charge stored in the second charge pump as a result of charging the second charge pump.

摘要： Systems and techniques for accessing a memory, such as a NAND or NOR flash memory, involve storing an operating application for a computing device in a first memory and storing a driver containing software operable to control the first memory in a second memory that is independently accessible from the first memory. By storing the driver in a second memory that is independently accessible from the first memory, changes to the driver and/or the first memory can be made without altering the operating application.

摘要： Systems and methods, including computer software for writing to a memory device include applying charge to each of multiple memory cells for storage of a selected data value in each memory cell. The memory cells include a first reference memory cell, and each data value is selected from a group of possible data values. Each possible data value has a corresponding target voltage level, and the first reference memory cell has a corresponding predetermined first reference target voltage level. The voltage level in the first reference memory cell is detected. A determination is made whether the voltage level in the first reference memory cell is less than the first reference target voltage level. Additional charge is applied to the memory cells upon the determination that the voltage level in the first reference memory cell is less than the first reference target voltage.
