Unit cell of nonvolatile memory device and nonvolatile memory device having the same

摘要

A One-Time Programmable (OTP) unit cell and a nonvolatile memory device having the same are disclosed. A unit cell of a nonvolatile memory device includes: an anti-fuse connected between an output terminal and a ground voltage terminal; a first switching unit connected to the output terminal to transfer a write voltage to the output terminal; and a second switching unit connected to the output terminal to transfer a read voltage to the output terminal.
