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
on
low RESET. All flash memory operations are synchronous to the rising edge of CLK.
