  • Publication number: 20030122578
    Abstract: A programmable logic device with ferroelectric configuration memories storing multiple configuration data sets. The device has programmable logic blocks, interconnections, and I/O blocks to provide desired logic functions. Those building blocks can be dynamically reconfigured by changing the selection of configuration data stored in the device's integral configuration memories. The configuration memories are divided into groups, so that they can be loaded concurrently with multiple configuration data streams. To protect the content of configuration memories from unauthorized access, the device employs an authentication mechanism that uses security IDs stored in the configuration memories. The device has a memory controller to provide an appropriate power supply sequence for ferroelectric memory cells to ensure the reliable data retention when the device is powered up or shut down.
