Abstract (in Japanese) (See Japanese page) 
(in English) We have been studied the via-programmable-device VPEX (Via Programmable logic using EXclusive or array) whose logic element consists of the combination of complex-gate-type EXOR gate and Inverter. 12 kinds of logic functions including all two-input and one-output functions can be programmed by changing via-1 layout. Various kinds of combination logics are configured by changing via-3 layout which controls the connection between LEs. Register (DFF: D Flip Flops) can be realized by using some LEs, so sequential-logic is also programmed in the LE array. In this study, we have designed the test chip which has small-scale circuits using VPEX architecture, and check the operation of each logic functions. We improved the elements of LE and realized the decrease of circuit area. As an example of circuit implementation, we applied VPEX architecture to DES encryption circuit, and evaluated the chip area of VPEX compared to that of Standard Cells.
