There are many kinds of ROM chips, or "Read Only Memories"

and ROM could refer to a chip that has some data in it

that you can only read - there is no way to write it or change it

so that the chip is manufactured in a way that it has that

ultraviolet light or do anything special.

basically the same. So this is sixteen thousand bits,

which is organized as two thousand 8-bit words or

eight I/O pins, so 0, 1, 2, 3, 4, 5, 6, 7 so eight I/O pins that's for

output for reading from it and then there are

telling it which byte we want to read, or

write if we're writing to it for programming it.

straightforward. There's ground and power for

"Write Enable", "Output Enable" and "Chip Enable",

pin 18 which is the "Chip Enable", and I'll hook

is enabled and we always want the chip to be

to ground. Next to note is there's are 8 I/O lines, so

I/O 0, 1, 2, 3, 4, 5, 6 and 7 so I'm going to hook those up to

stored in the chip. So I'm gonna add some LEDs

Alright, so there's 8 LEDs that we'll use for

looking at the data. Now I'll connect the data

here, and pin 11, and I/O 3 I'll connect over

So I've connected all these I/O lines to the LEDs so we'll be

able to see the output of the chip, but we
