    摘要: A non-volatile memory device has a charge pump for providing a programming current and an array of non-volatile memory cells. Each memory cell of the array is programmed by the programming current from the charge pump. The array of non-volatile memory cells is partitioned into a plurality of units, with each unit comprising a plurality of memory cells. An indicator memory cell is associated with each unit of non-volatile memory cells. A programming circuit programs the memory cells of each unit using the programming current, when fifty percent or less of the memory cells of each unit is to be programmed, and programs the inverse of the memory cells of each unit and the indicator memory cell associated with each unit, using the programming current, when more than fifty percent of the memory cells of each unit is to be programmed.

    摘要: An integrated circuit die has a first die pad for receiving a first voltage and a second die pad for receiving a second voltage. The second voltage is less than the first voltage. A first circuit which is operable at the first voltage is in the integrated circuit die. A second circuit which is operable at the second voltage is in the integrated circuit die and is connected to the second die pad. A circuit that detects current flow from the second die pad is in the integrated circuit die. A switch is interposed between the first die pad and the first circuit to disconnect the first die pad from the first circuit in response to current flow detected by the circuit for detecting current flow.

    摘要: A non-volatile memory device that includes N planes of non-volatile memory cells (where N is an integer greater than 1). Each plane of non-volatile memory cells includes a plurality of memory cells configured in rows and columns. Each of the N planes includes gate lines that extend across the rows of the memory cells therein but do not extend to others of the N planes of non-volatile memory cells. A controller is configured to divide each of a plurality of words of data into N fractional-words, and program each of the N fractional-words of each word of data into a different one of the N planes of non-volatile memory cells. The controller uses a programming current and a program time period for the programming, and can be configured to vary the programming current by a factor and inversely vary the program time period by the factor.

    摘要: Digital multilevel memory systems and methods include a charge pump for generating regulated high voltages for various memory operations. The charge pump may include a plurality of pump stages. Aspects of exemplary systems may include charge pumps that performs orderly charging and discharging at low voltage operation conditions. Additional aspects may include features that enable state by state pumping, for example, circuitry that avoids cascaded short circuits among pump stages. Each pump stage may also include circuitry that discharges its nodes, such as via self-discharge through associated pump interconnection(s). Further aspects may also include features that: assist power-up in the various pump stages, double voltage, shift high voltage levels, provide anti-parallel circuit configurations, and/or enable buffering or precharging features, such as self-buffering and self-precharging circuitry.
