Table 1. Block RAM Switching Characteristics
Symbol	Description	Performance as a Function of Speed Grade and Operating Voltage (V_{CC_RAM})						Units
		0.88V (H)	0.80V (M)		0.80V (L)¹
		-2	-2	-1	-2LLI	-2LSE -2LLE	-1
Maximum Frequency
F_{MAX_WF_NC}	Block RAM (WRITE_FIRST and NO_CHANGE modes)	1000	850	800	650	650	615	MHz
F_{MAX_RF}	Block RAM (READ_FIRST mode)	850	725	675	550	550	510	MHz
Block RAM Clock-to-Out Delays
T_{RCKO_DO}	Clock CLK to DOUT output (without output register)	0.797	0.901	0.967	1.141	1.141	1.233	ns, Max
T_{RCKO_DO_REG}	Clock CLK to DOUT output (with output register)	0.234	0.262	0.280	0.333	0.333	0.362	ns, Max
The block RAM is power by the V_{CC_RAM} supply that operates at 0.80V in low (L) voltage operation, see Table 1 .
