An integrated circuit having a memory cell including a programmable resistor, and a method for addressing a memory cell including a programmable resistance
A module comprises a bus invert encoder (24) for determining whether a set of data bits should be inverted prior to transmission over a communication bus. The bus invert encoder (24) produces a bus invert signal BI which controls a selective inversion means (28), for example a multiplexer. A partial fault detection encoder (32) determines one or more temporary check bits from the set of data bits, substantially in parallel with the bus invert encoder (24). Thus, the one or more temporary check bits are determined based on the assumption that the set of data bits are to be transmitted without inversion from the selective inversion means (28). A logic unit (34) is provided for correcting the one or more temporary check bits, if necessary, based on the bus invert signal produced by the bus invert encoder (24). The module has the e advantage of enabling the temporary check bits to be determined in parallel with the bus invert encoding, thereby reducing latency, with the logic unit being used to correct the check bits, if necessary, prior to transmission over the communication bus.
