Non-volatile content addressable memory device having simple cell configuration and operating method of the same

Abstract

Disclosed are a non-volatile content addressable memory device having a simple cell configuration and/or an operating method thereof. The non-volatile content addressable memory device includes a plurality of unit cells, wherein each of the plurality of unit cells consists of or includes a first ferroelectric transistor and a second ferroelectric transistor The first and second ferroelectric transistors are of different types such as different electrical types from each other. The first and second ferroelectric transistors may be connected in series or in parallel to each other. The first and second ferroelectric transistors may share one word line and one match line. The first and second ferroelectric transistors may share one search line. One of the first and second ferroelectric transistors may be connected to a search line and the other one may be connected to a bar search line. The first and second ferroelectric transistors may share one match line.
