 		 #159134 - EEPROM implies EPROM
Responding to: ???'s previous message
But an EEPROM is an EPROM. There is nothing "in the rules" that EPROM must be something that is UV-eraseable, or something that may not be electrically eraseable.

More specifically: EEPROM is Electrically Eraseable PROM, while EPROM just says Eraseable PROM, with the supported erase operation undefined. Nothing would stop a magnetically eraseable or microwave-eraseable memory (or an electrically eraseable memory) from using the EPROM acronyme.

Of course, it would be a marketing blunder to sell an EEPROM chip under the EPROM description, since people would assume that it would not support ISP and IAP reprogramming.

MOVX doesn't work for writing.            01/01/70 00:00      
   It's a read-only memory            01/01/70 00:00      
      EEPROM            01/01/70 00:00      
         RAM-EPROM            01/01/70 00:00      
            That wouldn't be an EEPROM.            01/01/70 00:00      
            Look at Ferro-electric memory            01/01/70 00:00      
         Not wrong.            01/01/70 00:00      
            An EEPROM is an EPROM            01/01/70 00:00      
               Technically, but not in common usage of the term.            01/01/70 00:00      
                  Common use != Definition            01/01/70 00:00      
               Not quite ...            01/01/70 00:00      
                  No, it's not            01/01/70 00:00      
                  A datasheet that actually calls it a "UVEPROM"            01/01/70 00:00      
                     OK ... I stand corrected ...            01/01/70 00:00      
                        A link with EPROM <= EEPROM            01/01/70 00:00      
                        Not that generic!            01/01/70 00:00      
                           Magnetic core memory            01/01/70 00:00      
                           it is SERIAL EEPROM            01/01/70 00:00      
                              UVEPROM?            01/01/70 00:00      
                                 I think a part number would be the solution            01/01/70 00:00      
                                    Symmetric speed too.            01/01/70 00:00      
                           ta paidia paizei !!!            01/01/70 00:00      
            EEPROM implies EPROM            01/01/70 00:00      
               Today, it's the other way round.            01/01/70 00:00      
                  assumption < implication            01/01/70 00:00      
                  You missed the point!            01/01/70 00:00      
                     As one of my old tutors used to say...            01/01/70 00:00      
         Let's not confuse things further            01/01/70 00:00      
            You have also missed the point            01/01/70 00:00      
      Or...            01/01/70 00:00      
   Some Kind Like....            01/01/70 00:00      
      Non-Volatile Memory            01/01/70 00:00      
         or maybe the AT28C64B will work            01/01/70 00:00      
      You mean you want an NVRAM?            01/01/70 00:00      
   write eeprom            01/01/70 00:00      
      that may not be the problem            01/01/70 00:00      
         EPROM has special write-procedures            01/01/70 00:00      
   Check the write waveform timings!!!!!            01/01/70 00:00      
      How?            01/01/70 00:00      
         Source code to simulate MOVX...            01/01/70 00:00      
         Start with the datasheet ...            01/01/70 00:00
