Abstract
Systems and methods are disclosed herein in accordance with one or more embodiments of the present invention to provide programmable logic devices with non-volatile memory and a variable amount of distributed memory (e.g., in a cost-effective manner). For example, in accordance with an embodiment of the present invention, a programmable logic device includes a plurality of input/output blocks providing an input/output interface for the programmable logic device and a first and second plurality of logic blocks providing programmable logic functions, with only the second plurality of logic blocks further adapted to provide random access memory functions. A routing structure programmably interconnects the input/output blocks and the first and second plurality of logic blocks. Configuration memory cells store configuration data to configure the input/output blocks, the first and second plurality of logic blocks, and the routing structure, with at least one block of non-volatile memory to store configuration data that can be transferred to the configuration memory cells.
