Computer Chip Help!!!

I have these memory chips. EPROM BIOS chips to be exact. The serial number on the chip is 27C256. I know the "C" means that the chip is CMOS(Complimentary Metal Oxide Semiconductor) process instead of Bipolar. CMOS means it's a high-performance chip. The prefix 27 means that it's an EPROM memory of either 24 pins or 28 pins. Mine being the newer 28 pin EPROM. The last part tells it's capacity (ie. 256 means it's 256K something). In all, this serial number will tell you that the chip is an EPROM in CMOS process at 256K(bit or byte I'm not sure).

Here's the real question. When you talk about the chip itself, people say it's 32x8 organization. With this in mind, tell me if my EPROM is 256Kilobit or 256Kilobyte capacity.

Please note that a Kilobyte(1024Bytes) is 8(8Bits in a Byte) times more than a Kilobit(1024Bits).

Please reply telling me what capacity this EPROM is. I need to know. Thanks in advance.
