Abstract
A semiconductor device includes a semiconductor substrate, a memory gate, and a data storage element. The semiconductor substrate includes a memory well which has two source/drain regions and a channel region between the source/drain regions. The memory gate is disposed above the channel region. The data storage element includes a ferroelectric material, and is disposed around the memory gate to separate the memory gate from the channel region.
