A semiconductor memory device capable of performing a package test with
bandwidth other than the default bandwidth without any wiring
modification with respect to package option pads reduces package test
time. The present invention implements the other package options based
upon the wire bonding with an internal option. According to the operation
mode, buffer control signals are used to control a VDD or VSS applied to
the package option pads via the wire bonding. Buffer control signal are
generated using a mode register reset. The buffer receiving the buffer
control signal outputs the signal corresponding to the wiring state of
the package option pad, blocks the signal path from the package option
pads, and outputs a signal corresponding to a package option other than
the default package option.
