Patent ID: 7994815

Claim:
A cross-point latch comprising: a signal line; two control lines crossing the signal line; and unipolar switches disposed at crossing points between the signal line and the control lines, wherein the cross-point latch is configured to output a signal corresponding to a first logic to the signal line through one of the two control lines and a corresponding unipolar switch after inputting a signal for the first logic to the signal line, and the unipolar switches are configured to open by applying a voltage between an ‘open 1’ and a ‘close 1’ to the unipolar switches or by applying a voltage between an ‘open 0’ and a ‘close 0’ to the unipolar switches, and close by applying a voltage greater than the ‘close 1’ or smaller than the ‘close 0’ to the unipolar switches, the ‘open 1’ and the ‘close 1’ being greater than a ‘ground’ voltage, the ‘open 0’ and the ‘close 0’ being smaller than the ‘ground’ voltage, the ‘open 1’ being smaller than the ‘close 1’, and the ‘close 0’ being smaller than the ‘open 0’.
