Abstract: An electrical contact is provided for an electrical connector that is mounted on a printed circuit. The electrical contact includes a mating segment having a mating interface configured to engage a mating contact of another connector. The electrical contact also includes a tail segment having a mounting interface configured to be mounted to the printed circuit. An intermediate segment extends between and interconnects the mating and tail segments. The intermediate segment includes a base wall extending a length from the tail segment to the mating segment. The intermediate segment further includes a side wall extending outwardly from the base wall along at least a portion of the length of the base wall. The side wall extends outwardly at a non-parallel angle relative to the base wall for affecting at least one of an impedance, an insertion loss, or a reflection of the electrical contact.

Abstract: Sensing circuits for sensing a conduction current of a memory cell among a group of non-volatile memory cells being sensed in parallel and providing the result thereof to a data bus are presented. A precharge circuit is coupled to a node for charging the node to an initial voltage. An intermediate circuit is also coupled to the node and connectable to the memory cell, whereby current from the precharge circuit can be supplied to the memory cell. The circuit also includes a comparator circuit to perform a determination the conduction current by a rate of discharge at the node; a data latch coupled to the comparator circuit to hold the result of said determination; and a transfer gate coupled to the data latch to supply a result latched therein to the data bus independently of the node. This arrangement improves sensing performance and can help to eliminate noise on the analog sensing path during sensing and reduce switching current.

Abstract: In sensing a page of nonvolatile memory cells with a corresponding group of sense modules in parallel, as each high current cell is identified, it is locked out from further sensing while others in the page continued to be sensed. The sense module involved in the locked out is then in a lockout mode and becomes inactive. A noise source from the sense module becomes significant when in the lockout mode. The noise is liable to interfere with the sensing of neighboring cells by coupling through its bit line to neighboring ones. The noise can also couple through the common source line of the page to affect the accuracy of ongoing sensing of the cells in the page. Improved sense modules and method isolate the noise from the lockout sense module from affecting the other sense modules still active in sensing memory cell in the page.

Abstract: A method is presented of setting a frequency of a clock for a charge pump system including the clock and a charge pump. This includes setting an initial value for the frequency of the clock and, while operating the charge pump system using the clock running at the initial frequency value, determining the ramp rate of an output voltage for the charge pump during a recovery phase. The frequency of the clock is then adjusted so that the ramp rate of the output voltage for the charge pump during the recovery phase falls in a range not exceeding a predetermined maximum rate. A charge pump system is also described that includes a register having a settable value, where the charge pump clock frequency is responsive to the register value, and count and comparison circuitry is connectable to receive the pump's output voltage and the clock signal and determine from them the number of clock cycles the charge pump uses to recover from a reset value to a predetermined value.

Abstract: In a sensing method, accuracy of sensing operations, such as read or verify, in a memory device is improved by avoiding fluctuations in a sense amp supply voltage which can occur when different sense amps are strobed at different times. First and second sets of sense amps perform a sensing operation on respective storage elements, such as in an all bit line configuration. The first set of sense amps is strobed at a first time point. In response, a sensed analog level is converted to digital data. The A/D conversion relies on the sense amp supply voltage being accurate. To avoid a fluctuation in the sense amp supply voltage, a bypass path allows the storage elements associated with the first set of sense amps to continue to draw power from the sense amp supply voltage. The second set of sense amps is strobed at a later, second time point.
