    摘要: A memory system comprises a memory controller, an address RAM coupled to the memory controller, and a non-volatile memory coupled to the memory controller. The non-volatile memory has an address portion and a data portion. The address portion of the non-volatile memory provides data portion addresses and data portion addresses of valid data to the memory controller. The memory controller loads the data portion addresses and stores them in the address RAM at locations defined by the data portion addresses of valid data into the address RAM. The memory controller uses the data portion addresses, and locations of data blocks within the address RAM, to locate the data blocks within the data portion of non-volatile memory. The memory controller uses the data portion addresses, and locations of the data block addresses within the address RAM, to locate data blocks within the data portion of non-volatile memory

    摘要: Methods and systems are disclosed for sector-based regulation of program voltages for non-volatile memory (NVM) systems. The disclosed embodiments regulate program voltages for NVM cells based upon feedback signals generated from sector return voltages that are associated with program voltage drivers that are driving program voltages to NVM cells within selected sectors an NVM array. As such, drops in program voltage levels due to IR (current-resistance) voltage losses in program voltage distribution lines are effectively addressed. This sector-based regulation of the program voltage effectively maintains the desired program voltage at the cells being programmed regardless of the sector being accessed for programming and the number of cells being programmed. Sector return voltages can also be used along with local program voltages to provide two-step feedback regulation for the voltage generation circuitry. Test mode configurations can also be provided using test input and/or output pads.

    摘要: A set of reference cells is used for sensing the data values stored at bit cells of a memory device. In response to an event, the reference cell providing the highest output of the set is selected as the reference cell to be used for subsequent memory access operations. The remaining reference cells are disabled so that they can recover back to or near their original non-degraded states. At each successive event, the set of reference cells can be reassessed to identify the reference cell that provides the highest output at that time and the memory device can be reconfigured to utilize the reference cell so identified. By utilizing the reference cell having the highest output to provide the read reference and disabling the remaining reference cells, the likelihood of the read reference falling below a minimum threshold can be reduced.

    摘要: A method of programming a split gate memory applies voltages differently to the terminals of the selected cells and the deselected cells. For cells being programming by being coupled to a selected row and a selected column, coupling the control gate to a first voltage, coupling the select gate to a second voltage, programming is achieved by coupling the drain terminal to a current sink that causes the split gate memory cell to be conductive, and coupling the source terminal to a third voltage. For cells not being programmed by not being coupled to a selected row, non-programming is maintained by coupling the control gate to the first voltage, coupling the select gate to a fourth voltage which is greater than a voltage applied to the select gate during a read in which the split gate memory cells are deselected but sufficiently low to prevent programming.

The pumpcells are coupled together in series including a first pumpcell receiving an input voltage and at least one remaining pumpcell including a last pumpcell which generates an output voltage. Each bypass switch is coupled to selectively provide the input voltage to a pumpcell input of a corresponding one of the remaining pumpcells. The control logic is configured to determine one of multiple voltage ranges of the input voltage, to enable each pumpcell for a first voltage range and to disable and bypass at least one pumpcell for at least one other voltage range. A method of operating a multistage charge pump including detecting an input voltage, selecting a voltage range based on an input voltage, and enabling a number of cascaded pumpcells corresponding to the selected voltage range.
