    摘要: In an embodiment, a non-volatile memory array wherein narrow word lines, as small as the minimum feature size width F, in separate strings, are extended outwardly from a non-volatile memory array and joined by wider connector segments. The joined word lines provide new opportunities. First, metal straps that can be formed to overlie the word lines can be joined by metal connector segments to the word lines. The connector segments can serve as an interface between the polysilicon word lines and the metal straps. Two adjacent word lines in the same string share a single metal strap using these segments thereby reducing the overall number of segments and contacts in the array. Increased width of the polysilicon joinder segments joining word lines in different strings, provides the opportunity for widening the connection beyond the minimum feature size so that contact may be readily made between the metal straps and the polysilicon word lines. Second, the joined word lines require fewer row decoder circuits. One row decoder is provided for each joined set of word lines.

    摘要: A regulated charge pump circuit having two-way switching means that switches between a first feedback pathway that provides a precise and stable voltage output and a second feedback pathway that provides a regulated voltage output with low current consumption from the power source. The first feedback pathway maintains a precise voltage output by regulating a pass device that draws current to the voltage output. The second feedback pathway regulates the voltage output by controlling the connection of a clock input to the charge pump. A variable resistor is used to set the regulated level of the voltage output. A digital-to analog converter is formed by using a combination logic circuit to convert a digital input signal to a control signal for the variable resistor.

    摘要: A sense amplifier circuit for reading the state of memory cells. In one aspect of the invention, the sense amplifier circuit includes a first stage receiving a cell current derived from the memory cell and a reference current derived from a reference cell, and a second stage receiving the cell current and the reference current. A comparator, coupled to the first stage and the second stage, provides an output indicative of the state of the memory cell based on a difference of the voltages provided by the first stage and the second stage, where the state indicated by the comparator is substantially unaffected by capacitive current components provided by transient behavior of the first and second stages.
