Title: Nonvolatile memory
Inventor: SHIROTA SHOZO
IPC: H01L27/115
Filed: 1992-02-28
Abstract: PURPOSE:To obtain a nonvolatile memory in which a restriction in a pattern shape is eliminated and reliability after irradiation with ultraviolet ray is emitted is improved by covering a memory cell of a UPROM with a PIX film. CONSTITUTION:If an ultraviolet ray for erasing information of an EPROM is emitted, a memory cell of the EPROM in which information is not desired to be erased is covered with a PIX film which does not transmit the ray. Thus, the ray does not reach the cell formed of an oxide film 4, a control gate 5, a floating gate 6, an n<+> type source 7, an n<+> type drain 8 and a P-type silicon substrate 9, and the information of the cell is not erased. Accordingly, since the cell of an UPROM is covered with the PIX film, the cell can be covered in a wide range without restriction in the formation of a pattern, and reliability of an operation after the ray is emitted can be improved.

Abstract: PURPOSE:To recognize whether the number of times of the discords of a password number reaches a cumulative upper limit value or not by outputting a negative response data when a prescribed relation is not present between a second externally inputted data train and a first data train stored in a memory part. CONSTITUTION:For instance at the time of the discord of the collation of the password number, the cumulative value of the number of times of the discords is compared with the cumulative upper limit value, and when the cumulative value does not reach the cumulative upper limit value, a first discord information (first negative response data) is outputted and when the cumulative value reaches the cumulative upper limit value, a second discord information (second negative response data) is outputted. Thereby, even when an external device does not already know the cumulative upper limit value of the password number to be collated, whether the number of times of the discords reaches the cumulative upper limit value or not can be recognized. Accordingly, for instance, a security as an IC card system can be maintained to apply no burden on a control as the external device even by registering the plural password numbers.
