    摘要: There is provided a non-volatile memory capable of being supplied with two varieties of externally supplied voltages, stabilizing the operation thereof, at a voltage in the vicinity of a threshold voltage for switching over between the externally supplied voltages, and stabilizing the operation thereof, at the times of writing and erasing, respectively. The non-volatile memory comprises a power supply circuit incorporating a hysteresis comparator having two voltage levels for the threshold voltage, wherein by detection of 2.3V at a time when an externally supplied voltage rises, a detection signal goes to an “H” level, whereupon an internal step-down circuit, made up of a constant voltage circuit, and so forth, comes into action, generating an internal operation voltage at 2.2V to be subsequently supplied, and thereafter, by detection of 2.1V, the detection signal goes to an “L” level, whereupon the externally supplied voltage, as it is, is supplied as the internal operation voltage. Accordingly, since the detection signal remains in the “H” condition even when the externally supplied voltage is unstable in the vicinity of 2.3V, the internal operation voltage does not undergo variation.

The channel region 104 having a first impurity concentration determined by a surface concentration of a P-type semiconductor substrate and a channel region 105 having a second impurity concentration determined by doping an impurity to the region selected by a pattern 106 of a mask for doping impurity by ion implantation and others are provided in a channel region of an N-type MOSFET on the P-type semiconductor substrate. The channel region 104 having the first impurity concentration and the channel region 105 having the second impurity concentration are divided into a plurality of plane shapes. The channel region of the same MOSFET may be structured by the plurality of plane shapes having the plurality of impurity concentrations as described above and a threshold voltage of the MOSFET may be readily set to a desired value in response to a plane area ratio of the area having the first impurity concentration and the area having the second impurity concentration, allowing to realize a high performance semiconductor integrated circuit device at low cost.
