Abstract
The present application discloses a multi-time programmable electronic fuse apparatus, including: a one-time programmable cell module, a parsing module and a multi-time programmable cell module. The one-time programmable cell module is configured to store one-time programmable data, the multi-time programmable cell module includes a storage cell array capable of reading and writing data multiple times and is configured to store multi-time programming data. The parsing module is configured to read the one-time programming data transmitted from the one-time programmable cell module, to write the parsed initialization data into the multi-time programmable cell module upon reading the initialization data; to parse the fix data to obtain a fix location and a fix value upon reading the fix data, and to replace data stored in the corresponding fix location in the storage cell array with the fix value.
