What is an EEPROM?
Electrically Erasable Programmable ROM or EEPROm is a rewritable memory chip that holds its content without power. The two main categories of EEPROM interfaces are Serial bus and Parallel bus. These interfaces require between 1 and 4 control signals for operation, resulting in a memory device in an 8-pin (or less) package. Most common EEPPROM serial interface types are SPI, I²C, Microwire, UNI/O, and 1-Wire.  (Souce: EE Times, Wikipedia http://en.wikipedia.org/wiki/EEPROM)

2000-03-01 Taking new stabs at programmable analog
Programmable logic has some traditional advantages over ASIC design. The gate count of FPGAs approaches that of custom circuits. FPGAs can be programmed?and re-programmed?out in the field, enabling fast time to market. ASICs, in comparison, need careful attention to layout and fabrication technology. It can take anywhere from six weeks to two years (depending on the complexity of the circuit) to get an ASIC working properly.
