    摘要: An electrically programmable read only memory device formed in a face of a semiconductor substrate of a first conductivity type which includes a pair of spaced apart thick oxide isolation regions defining an elongated channel of the substrate therebetween. A floating gate of conductive material overlies a portion of one of the isolation regions and a first portion of the elongated channel being separated from the oxide isolation and channel regions by an insulator layer. A control layer of conductive material extends over the channel and the floating gate separated from both of the latter by an insulator layer. Buried diffused regions are located below each oxide isolation region.

    摘要: A method and apparatus for flash EEPROM refresh is provided in which the control gate of a particular memory cell is read at an elevated control gate voltage (42). It is next determined whether the cell has been programmed (44). If the cell has been programmed, then the next memory cell is read (46). If it is initially determined that the cell has not been programmed (44), then the particular memory cell is read at a lowered control gate voltage (48). It is then finally determined whether the cell has been programmed (50). If it is determined that the cell has not been programmed, then the next cell is read (46). If it is determined that the cell has been programmed (50), then the memory is refreshed (52). After refresh, the next memory cell is read (46).

    摘要: A programming implementation circuit for use in programming a floating-gate, avalanche-injection, metal-oxide-semiconductor integrated-circuit memory cell. The circuit is comprised of programming control means, a decoder switching means and an enabling means. A current-limiting input voltage is transmitted by the decoder switching means to the programming control means when the circuit is placed in one state by the enabling means, causing the control means to limit current during programming. When the cicuit is placed in a second state by the enabling means, the programming control means is deactivated and the bit line of the memory circuit is connected to a sense amplifier.

    摘要: An electrically programmable semiconductor memory device of a type having an array of programmable semiconductor floating gate transistors sets of which are coupled between associated respective source and drain lines, an array programming control transistor and a ground select transistor coupled to each of the drain and source lines. Each selected floating gate transistor in a programming mode is in series with control and ground select transistors between a high voltage Vpp and ground potential. A resistive element in series with a first conducting circuit element establishes a reference current which generates a voltage V.sub.1 at the junction of the resistive element and the circuit element. In a second current leg a second conducting circuit element, a module floating gate transistor biased into a conducting state and a module control transistor are all connected between Vpp and ground such that a voltage V.sub.2 is established at the junction of the second circuit element and the module floating gate transistor. Comparing means compares voltages V.sub.1 and V.sub.2 and adjusts the gate voltage V.sub.3 of the module programming control transistor so as to make the voltage V.sub.2 equal to voltage V.sub.1 and applies voltage V.sub.3 to the gates of the array programming control transistors. Since the transistor in the reference path is both electrically and geometrically the same as that in the second leg across which the voltage developed is compared, and is made by the same process, the current in the second leg will be substantially the same as that in the reference leg. Moreover, since the array floating gate transistors are also made by the same process as is the module floating gate transistor and the programming control and ground select transistors are also identical, by feeding the voltage V.sub.3 to array control transistors substantially the same current will flow through a selected array transistor as flows through both the reference current path and the second current leg.
