Abstract:
An integrated circuit including a ferroelectric random access memory (FRAM) for storing firmware, and a method of updating that firmware. The FRAM is constructed to selectively operate as a 2T2C FRAM memory in a normal operating mode, and as a 1T1C FRAM memory in an update mode. Updating of the stored firmware is performed by placing the FRAM in its update (1T1C) mode and writing the updated code into alternate rows of the 1T1C half-cells at each of a plurality of memory locations, while the other 1T1C half-cells in the other alternate rows retain the original data. Following verification of the updated contents, the original data in the other half-cells are overwritten with the verified updated data, and the operating mode is changed back to the normal (2T2C) operating mode.

Claim (Index 3):
The integrated circuit of  claim 2 , wherein the logic circuitry controls the FRAM, in the normal operating mode, to read the contents of one or more memory cells by a sequence of operations comprising:\n applying a row address to the decode circuitry; controlling the decode circuitry to select a row of the array of memory cells corresponding to the row address while masking the single row address bit; and operating one or more of the plurality of sense amplifiers to sense a differential signal between the first and second bit lines; and wherein, in the update mode, the verifying operation comprises reading the second data set from the second half-cells of the selected plurality of memory cells by: applying a row address to the decode circuitry; controlling the decode circuitry to select a row of the array of memory cells corresponding to the row address including the single row address bit; and operating one or more of the plurality of sense amplifiers to compare a signal at the second bit line with a reference voltage.
