Abstract
A random bit cell includes a selection transistor, a first P-type transistor, and a second P-type transistor. The selection transistor has a first terminal coupled to a source line, a second terminal coupled to a common node, and a control terminal coupled to a word line. The first P-type transistor has a first terminal coupled to the common node, a second terminal coupled to a first bit line, and a floating gate. The second P-type transistor has a first terminal coupled to the common node, a second terminal coupled to a second bit line, and a floating gate. During an enroll operation, one of the first P-type transistor and the second P-type transistor is programmed by channel hot electron injection.
