    摘要: A method for writing cells in a memory which reduces errors caused by depleted memory array cells being turned on even when not selected. In the method, nonselected bit lines and nonselected word lines are biased so that the threshold voltage of the nonselected cells increases. In particular, the nonselected bit lines are left floating and the nonselected word lines are set to a zero voltage. Appropriate potentials are applied to the selected word line, selected bit line, and selected source line in order to program the selected cell.

    摘要: In a flash-EEPROM array, the cells in each row are grouped into pairs connected to the same diffused source line and to two different diffused bit lines, and the adjacent pairs of cells are spaced so that, in each row, only one cell is connected to a respective diffused bit line. The array presents global bit lines in the form of metal lines, and each connected to a plurality of diffused local bit lines, at least one for each sector. For each sector and each global bit line, there are provided two diffused local bit lines connected to the same respective global bit line by selection transistors so that only one local bit line is biased each time.

    摘要: To reduce read and write errors caused by depleted memory array cells being turned on even when not selected, the nonselected memory cells are so biased as to present a floating terminal and a terminal at a positive voltage with respect to the substrate region. The threshold voltage of nonselected cells (i.e., the minimum voltage between the gate and source terminals for the cell to be turned on) increases due to a "body effect", whereby the threshold voltage depends on the voltage drop between the source terminal and the substrate. The source line of a selected cell is biased to a positive value greater than that of the bit line of the selected cell. Methods for reading, writing and erasing cells using certain voltage levels are disclosed.

    摘要: To reduce the supply voltage of a nonvolatile memory, a read reference signal is generated having a reference threshold value ranging between the maximum permissible threshold value for erased cells and the minimum permissible threshold value for written cells. To avoid reducing the maximum supply voltage, the characteristic of the read reference signal is composed of two portions: a first portion, ranging between the threshold value and a predetermined value, presents a slope lower than that of the characteristic of the memory cells and a second portion, as of the predetermined value of the supply voltage, presents the same slope as the characteristics of memory cells. The shifted-threshold, two-slope characteristic is achieved by means of virgin cells so biased as to see bias voltages lower than the supply voltage.
