Reconfigurable integrated circuit device and writing method thereof

摘要

A reconfigurable integrated circuit device includes a memory unit for storing configuration information. The memory unit has a nonvolatile memory transistor having a gate connected to a first wire, a first terminal connected to a second wire, and a second terminal connected to a third wire. The memory unit also includes a switch circuit connected to the third wire. The switch circuit alters the configuration of the integrated circuit device by, for example, opening and closing to make wiring connections or disconnections. The integrated circuit device additionally includes a data supply circuit for supplying bit data and a first power supply circuit for supplying voltages to the first wire for storing bit data in the first nonvolatile memory transistor and for storing bit data as a charge level on the third wire.
