WebApr 24, 2024 · That means that when the bit 8 of the address is high, the chip enable pin is activated, and the chip is enabled. The other address bus bits are connected as normal. The chip only sees the addresses as ranging from 0 to 255 as before, and works normally. In effect, bit 8 picks which of the two memory chips is addressed. In computing, a memory address is a reference to a specific memory location used at various levels by software and hardware. Memory addresses are fixed-length sequences of digits conventionally displayed and manipulated as unsigned integers.
