PROGRAMMABLE LOGIC CIRCUIT AND SEMICONDUCTOR DEVICE

Title:

PROGRAMMABLE LOGIC CIRCUIT AND SEMICONDUCTOR DEVICE

Document Type and Number:

Japanese Patent JP2002305439

Kind Code:

A

Abstract:

To provide a programmable logic circuit, capable of realizing a desired circuit using a small number of cells.

A switching module 11 is able to supply a fixed value to a logical block, and to connect adjacent wiring N, E, S, and W to each other. Therefore, it is possible to improve the flexibility in the arrangement of cells by directly connecting adjacent cells or global wiring, while executing logical arithmetic operations within the same cell.
