The _chips_ are 256K by 1 bit. You feed an 18 bit address into
Confusing correction (for the real hardware hackers here). These DRAMs
take the address in 2 halves of 9 bits each. You give the chip 9 bits of
the address, then the other 9 bits, and finally read/write 1 bit of data.
one chip and you get one data bit out. 9 chips form a
bank with
8 data bits plus a parity bit.
