Basic problem understanding EEPROM specs !!!

[arunb]

Hi All,

I have been going through EEPROM specs, the memory specs is given as

128K x 8 , does this mean that memeory is something like this

F F F F ........( 128x1024 times).


Also in some memory chips only the maximum capacity is given, like 24LC04B.

Kindly advise..

Thanks
arun

128k by 8 is 128kilo bytes. The chip itself will be advertised as a 1Mbit (128k entries by 8 bits wide, but it could just as easily be 64k by 16 bits wide :-)

I think you meant FF 128*1024 times. FFFF is 2 bytes.

If nothing else is given, other than the size, I always assume that the size is in KBits.

24LC04 will be a 3v part, 4 kbits = 512 bytes * 8 bit.

HTH

Pete.
