  • Patent number: 8947968
    Abstract: A memory has a normal mode and a power saving mode. The memory has bitline precharge circuitry which during the normal mode selectively couples a pair of bitlines to a precharge node to charge the bitlines to a given voltage level. During the power saving mode the bitlines are isolated from the precharge node. Voltage control circuitry is provided to maintain the precharge node at a first voltage level during the normal mode and at a second voltage level less than the first voltage level during the power saving mode. By reducing the voltage level at the precharge node during the power saving mode, the amount of inrush current occurring when switching from power saving mode to normal mode can be reduced, and this enables the wakeup time to be reduced when returning from power saving mode to normal mode.

  • Patent number: 8848412
    Abstract: A ternary content addressable memory (TCAM) has at least one TCAM cell comprising first and second memory bitcells for storing first and second bit values representing a cell state comprising one of a first cell state, a second cell state and a mask cell state. The first and second memory bitcells share a pair of bitlines for accessing the first and second bit values. Access control circuitry is provided for triggering, in response to a clock signal, a read or write access to the first memory bitcell during a first portion of a clock cycle and triggering a read access or write access to the second read bitcell during a second portion of the clock cycle.

  • Patent number: 7559772
    Abstract: An electrical connector is provided, which includes an insulative housing and a flexible bus inserted into the insulative housing. The insulative housing includes a base defining a slot therein, and a mating portion connected with the base. Mounting portions are integrally formed on opposite sides of the base for receiving fixing sheets. The flexible bus has a top surface and a bottom surface, the bottom surface forming a plurality of contact points on an end thereof. When the flexible bus extends into the slot of the insulative housing, contact points of the flexible bus are exposed out of a side of the mating portion for electrically connecting with a mating connector.

  • Patent number: 7438590
    Abstract: An electrical connector includes an insulative housing receiving a plurality of terminals therein, an upper cover mounted on the insulative housing, a flexible bus, and a casing shielding the upper cover and fixed to the insulative housing. The insulative housing has a mating portion for mating with a mating connector. The flexible bus has a plurality of contacts on an end thereof. The upper cover presses against the flexible bus in assembly, forcing the contacts to contact the terminals. The casing biases against the upper cover, forcing the contacts of the flexible bus to contact the terminals reliably. The flexible bus of the electrical connector does not contact a mating connector directly, thereby lengthening the life of the flexible bus even after repeated plugging.
