Abstract
In order to achieve rapid reconfiguration of logic elements in a programmable logic device, a plurality of memory logic modules are arranged in a two-dimensional array. At least one logic element is provided in each of the plurality of memory logic modules. The logic element is provided with a configuration memory into which configuration data can be written to specify logic functions of the logic element. A memory element is provided in each of the plurality of memory logic modules. The memory element stores a plurality of configuration data with respect to the logic element, and one of the plurality of configuration data is written into the configuration memory of the logic element to configure or reconfigure the logic element.
