Hi

I have an application that uses 4k external eprom (2732). I want to use
eeprom or flash instead to alter tables in the code. It appears that 4k
parallel eeprom or flash is not common, but 8k is like 28C64 or 28F64.

I don't have the ability to make program changes in addressing. All I want is
to change values in lookup tables quickly via serial programming link. I may
only need to change a couple of bytes at a time. I want to create a small
module that plugs into the 4k eprom dip socket and has eeprom with serial
programming hardware on the module.

My question - Can I use an 8K external eeprom as a direct replacement of a 4k
eprom?

I think it would be okay, it will just use 4k of the 8k eeprom.

All I have used before is serial eeproms. Can you program a few individual
addresses using a 28C64 eeprom?

Thanks

Jon
