PROGRAMMABLE LOGIC DEVICE WITH FERROELECTRIC CONFIGURATION MEMORIES

摘要

The present invention relates to a programmable logic device having a ferroelectric memory configured to store a plurality of configuration data sets. The device has a programmable logic block, interconnections and I / O block that can provide the logic function desired. These building blocks can be dynamically reconfigured by changing the selection of the configuration data stored in configuration memory of the integrated device. Configuration memories are divided into groups, a plurality of configuration data streams can be simultaneously loaded. In order to protect the contents of the configuration memory from unauthorized access, the device employs an authentication mechanism using a secure ID that is stored in the configuration memory. The device is a ferroelectric memory cell to have a memory controller which provides the appropriate power supply sequence to ensure the power-up or shutdown of the device to maintain the data.
