Abstract: The present disclosure is directed to a sense amplifier architecture for a memory device having a plurality of memory cells. Groups of non-volatile memory cells store respective codewords formed by stored logic states, logic high or logic low, of the memory cells of the group. The sense amplifier architecture has a plurality of sense amplifier reading branches, each sense amplifier reading branch coupled to a respective memory cell and configured to provide an output signal, which is indicative of a cell current flowing through the same memory cell; a comparison stage, to perform a comparison between the cell currents of memory cells of a group; and a logic stage, to determine, based on comparison results provided by the comparison stage, a read codeword corresponding to the group of memory cells. Information may be stored in different subsets of codewords, the sense amplifier architecture in this case having a subset definition circuit, to allow a preliminary determination of the subset to which a codeword to be read belongs to, based on reference signals.

Abstract: A method of operating a radio transmitter configured to transmit at least one sequence of logic values by transmitting transmission signals selected in a constellation diagram having a certain cardinality comprises selecting said transmission signals out of a first subset of transmission signals in said constellation diagram, said first subset comprising a first number of transmission signals, and a second subset of transmission signals in said constellation diagram, said second subset comprising a second number of transmission signals, wherein. The transmission signals in the second subset of transmission signals have an energy higher than the transmission signals in the first subset of transmission signals. The sum of said first number of transmission signals and said second number of transmission signals is less than said cardinality.
