Embedded Memories
Fusion devices include four types of embedded memory: flash block, FlashROM, SRAM, and FIFO.
Flash Memory Block
Fusion is the first FPGA that offers a flash memory block (FB). Each FB block stores 2 Mbits of data. The flash memory
block macro is illustrated in
All flash memory block signals are active high, except for CLK and active low RESET. All flash memory operations are
synchronous to the rising edge of CLK.
