    Abstract: Methods and devices for adjusting a read threshold voltage of bitlines are provided. One such method includes adjusting a read threshold voltage of bitlines coupled to memory points of a memory circuit. The read threshold voltage is initially set to a first value. First data are written in the memory points and second data are read from the memory points. The second data are compared to the first data, and the threshold voltage is decreased by a second value in response to a comparison error of one of the second data with the corresponding first data.

    Abstract: A radio frequency module with common access point (1) comprising a common access point (2) adapted to send and receive radio frequency signals, said common access point (2) having a common access point impedance, a first radio frequency communication circuit (6) and a second radio frequency communication circuit (8), a first balun (10) coupled to the first radio frequency communication circuit (6) by first ports (11a, 11b) wherebetween a first impedance (Z1) varying between a high value and a low value is established, and a second balun (20) coupled to the second radio frequency communication circuit (8) by second ports (21a, 21b) wherebetween a second impedance (Z2) varying between a high value and a low value is established, wherein the radio frequency module with common access point (1) comprises an impedance matching circuit (18) connected between the first ports (11a, 11b) in parallel with the first balun (10), and a switch (16) configured to open and close the impedance matching circuit (18).

    Abstract: A method for determining a distance offset between a depth map of an indirect time-of-flight measurement device and a reference ground truth map includes emitting emission optical radiation by an emission circuit of the indirect time-of-flight measurement device. The emission optical radiation is sequentially modulating by N modulation frequencies. N is greater than or equal to three. The method further includes receiving, by a reception circuit of the indirect time-of-flight measurement device, reception optical radiation generated by the emission optical radiation reflected off objects of a scene and by optical crosstalk between the emission optical radiation and the reception optical radiation, and estimating the distance offset based on the reception optical radiation.

    Abstract: A memory includes memory cells arranged in rows and in columns, with at least one bit line for each column being coupled to the memory cells of the column. A read/write circuit is coupled to the bit lines and is configured to receive, for each column, a binary datum to be stored in one of the memory cells of the column. The read/write circuit includes, for each column, a latch configured to store a bit of a key, and an encryption circuit configured to encrypt the received binary datum with the bit of the key to provide encrypted binary datum. The read/write circuit controls the bit line to thereby store the encrypted binary datum.
