Abstract: A non-volatile memory includes a row decoder comprising, for each word-line, a respective pull-up connected to a first supply voltage and a switching circuit for selectively connecting one of the word-lines to ground. The row decoder comprises a demultiplexer connected to a second supply voltage smaller than the first, and configured to assert an enable signal as a function of an address signal. The switching circuit comprises two n-channel FETs connected in series between the word-line and ground, with the gate terminal of one FET connected to a first signal and the gate terminal of the other FET connected to a second voltage. A bias circuit is configured to set the voltage between the two FETs to the second voltage when the FETs are opened. The switching circuit comprises a p-channel FET connected between the word-line and the second voltage, and a gate terminal connected to a second signal.

Abstract: A structure including a base portion (e.g., made of a graphite-based or graphene-based material) with at least one surface that is coated with a homogenous coating layer (e.g., made of silicon-carbide (SiC)). The homogenous coating layer prevents contaminants (e.g., carbon) from being released by the base portion into a cavity of a processing tool when heated to process one or more workpieces (e.g., silicon substrate, silicon wafers, etc.) present within the cavity. The homogenous coating layer includes grains and grain boundaries that are relatively the same size and shape as each other, which further prevents propagation of defects (e.g., cracking, peeling, etc.) that could potentially cause exposure of a region of the first surface of the base portion to the cavity of the processing tool contaminating the one or more workpieces present within the cavity of the processing tool.

Abstract: A test-circuit includes a PLL-divider outputting first and third clock-signals as PLL clock-signals during functional mode and a capture-phase of transition and stuck-at-modes, and outputting a second clock-signal based upon an external clock-signal as an ATE clock-signal during a shift-phase of the transition and stuck-at-mode. An OCC passes the clock-signals in functional mode, transition capture mode, and stuck-at capture mode through sub-paths within first paths within first and second clock selection circuits so the first and third clock-signals are passed through less than the entire first paths, the sub-paths being first and second functional clock paths. In shift phase of transition and stuck-at-modes, the OCC passes the second clock-signal through sub-paths within second paths within the first and second clock selection circuits during the shift-phase so the second clock-signal is passed through less than the entire second paths, and through the first and second functional clock paths during the shift-phase.

Abstract: Disclosed herein is a method of operating a static random access memory (SRAM) device in retention mode. The method includes powering an array of SRAM cells between first and second voltages in retention mode, detecting process variation information about the array of SRAM cells, and generating a control word based thereupon. The method continues with generating a reference voltage that is proportional to absolute temperature and having a magnitude curve that is set by the control word, and then maintaining the second voltage as being equal to the reference voltage.

Abstract: A circuit includes a memory array with SRAM cells connected in rows by word lines and in columns by bit lines. A row controller circuit simultaneously actuates, through a word line driver circuit for each row, word lines in parallel for an in-memory compute operation. A column processing circuit processes analog voltages developed on the bit lines in response to the simultaneous actuation to generate a decision output for the in-memory compute operation. A bit line clamping circuit includes a sensing circuit that compares the analog voltages on a given pair of bit lines to a threshold voltage. A voltage clamp circuit is actuated in response to the comparison to preclude the analog voltages on the given pair of bit lines from decreasing below a clamping voltage level.

Abstract: A debug method implemented by a first near field communication (NFC) device includes a step of storing, in a memory of the first NFC device, one or more parameters which are associated with the operation of the first NFC device during a communication with a second distant NFC device. The first NFC device then uses an answer to select (ATS) communication, sent in response to receipt of an answer to select (ATS) communication, to send the stored one or more parameters to the second distant NFC device.

Abstract: A memory system includes a memory with memory blocks. A first logic circuit performs an XOR combinational logic function of a current value of a data addressing mode and of at least one bit of a first data packet including an error correction code of a data element to be written. A second data packet, generated by the first logic circuit, is stored into one of the memory blocks. A second logic circuit performs an XOR combinational logic function of at least one bit of the second packet (such as read from one of the memory blocks) and of the current value of the addressing mode. A weight of the bit of the first data packet corresponds to a weight of the at least one bit of the second read data packet.
