Hence, reducing … WebApr 1, 2011 · For example, if address 0 is pre-initialized to FF, the RAM block powers up with the output at 0. A subsequent read after power-up from address 0 outputs the pre-initialized value of FF. Therefore, if a RAM powers up and an enable (read enable or clock enable) is held low, the power-up output of 0 maintains until the first valid read cycle.
