ABSTRACT:
A semiconductor memory device in which a stored information can be simply erased only by an electric signal so as to be rewritten is provided. The semiconductor memory device includes (a) a semiconductor chip having an array of memory cells, stored information in the memory cells being erasable by light irradiation; (b) a light emitting element irradiating a light into the memory cells portion of the semiconductor chip; and (c) a package in which the semiconductor chip and the light emitting element are encapsulated with a resin in one body.
