Message: Actel Powers Down – Again--echoes of doni

"This part may be with the help of MICRO-OS"

"On static power, flash already has a significant advantage over its SRAM-based rivals. For an SRAM FPGA to stay alive, it needs to power a lot of SRAM cells just to hold its configuration – the state of the routing and look-up-table (LUT) truth tables. True flash-based FPGAs keep this same configuration information in flash cells which, of course, require no power to retain their state. The majority of static power in a programmable logic device is consumed by keeping the configuration intact, so flash-based FPGAs can have a couple orders of magnitude advantage in static power over even the thriftiest of SRAM-based devices."

The power concern is important ,however, the highlight above is the question. Previously that logic was managed within DRAM, SDRAM,SRAM.....now it's managed within the flash.

The SRAM is now being utilized with a tiny foot print to pass the signals from the flash to the processor.

e.Digitals patents are of this nature.
