Hi All .. Continuing my learning curve on using different types of memories I have finally alighted on parallel 128k x 8bit eeprom. ( 28F010 flash ) I will be using the chip in a data logging application My question's are these - Is it necessary to erase the complete chip(s) before using it again ? How do I write to the command register ? If someone could help me with the last problem I think that would be my big break - I would then figure out the rest myself. Is there any code available ??
