摘要： A system includes a memory controller and a plurality of semiconductor devices that are series-connected. Each of the devices has memory core for storing data. The memory controller provides a clock signal for synchronizing the operations of the devices. Each device includes a phase-locked loop (PLL) that is selectively enabled or disabled by a PLL enable signal. In each group, the PLLs of a selected number of devices are enabled by PLL enable signals and the other devices are disabled. The enabled PLL provides a plurality of reproduced clock signals with a phase shift of a multiple of 90° in response to an input clock signal. The data transfer is synchronized with at least one of the reproduced clock signals. In the devices of disabled PLLs, the data transfer is synchronized with the input clock signal. The enabled PLL and disabled PLL cause the devices to be the source and the common synchronous clocking, respectively. The devices can be grouped. The devices of one group can be structured by multiple chip packages.

摘要： A ternary content addressable memory (CAM) cell is disclosed for providing reduced or minimized matchline (ML) capacitance and for increasing current between matchline and tail-line in the case of a mismatch. The speed of a CAM cell is generally inversely proportional to its ML capacitance, and proportional to the current. Conventional ternary CAM cells have many matchline transistors, each contributing to the matchline capacitance. Embodiments of the present invention have a single matchline transistor between a matchline and a ground line, or tail-line, of the CAM cell. The single matchline transistor couples the matchline to the tail-line in response to a discharge signal from a compare circuit. The compare circuit can be divided into a pull-up section for driving a gate voltage level control node and a discharge section for discharging the gate voltage level control node, the discharge signal being provided at the gate voltage level control node.

摘要： A symmetric finite impulse response filter for receiving a digital input signal and generates a filtered analog output signal for application to a balanced line, such as a tip and ring lead pair. Logic levels of predetermined symmetrical bit pairs of the digital input signal are detected and in response, predetermined corresponding capacitors are selectively switched between bias and reference voltages, thereby charging predetermined voltages proportional to the capacitances of the capacitors. The predetermined voltages are summed in an operational amplifier which, in response produces a filtered analog output signal. Individual capacitors are utilized for realizing each pair of symmetrical coefficients of the filter transfer function, resulting in considerable economy of size. A switched capacitor implementation results in high speed performance, simple design and low cost.
