Abstract
A differential sensing device includes two reference cells, four path selectors, and four sample circuits. The first path selector is coupled to a first sensing node, the second reference cell, and a first memory cell. The second path selector is coupled to a second sensing node, the first reference cell, and the first memory cell. The third path selector is coupled to a third sensing node, the first reference cell, and a second memory cell. The fourth path selector is coupled to a fourth sensing node, the second reference cell, and the second memory cell. During a sample operation, the first sample circuit samples a first cell current, the second sample circuit samples the first reference current, the third sample circuit samples a second cell current, and the fourth sample circuit samples the second reference current.
