WitrynaA NAND gate is an inverted AND gate. It has the following truth table: A CMOS transistor NAND element. V dd denotes positive voltage. In CMOS logic, if both of the A and B … One limitation of flash memory is that it can be erased only a block at a time. This generally sets all bits in the block to 1. Starting with a freshly erased block, any location within that block can be programmed. However, once a bit has been set to 0, only by erasing the entire block can it be changed back to 1. In other words, flash memory (specifically NOR flash) offers random-access rea…
