摘要： In one embodiment of the invention, a block of configuration memory has rows of memory cells, at least one row having a set of one or more dual-port memory cells adapted to selectively store either configuration data or local data. The configuration address line for that row is segmented such that the address line is connected to the configuration address ports of the dual-port memory cells via access control circuitry that can be programmably configured to prevent access to those memory cells via the configuration address line. The access control circuitry enables local data to be efficiently and accurately stored in the dual-port memory cells without interference from configuration readback operations during normal operation or from partial reconfiguration of the configuration memory.
