摘要： A system has a first plurality of cores in a first coherency group. Each core transfers data in packets. The cores are directly coupled serially to form a serial path. The data packets are transferred along the serial path. The serial path is coupled at one end to a packet switch. The packet switch is coupled to a memory. The first plurality of cores and the packet switch are on an integrated circuit. The memory may or may not be on the integrated circuit. In another aspect a second plurality of cores in a second coherency group is coupled to the packet switch. The cores of the first and second pluralities may be reconfigured to form or become part of coherency groups different from the first and second coherency groups.

摘要： A double-rate memory has an array of single word line memory cells arranged in rows and columns. The single word line memory cells provide and store data via a first port. Addressing and control circuitry is coupled to the array of single word line memory cells. The addressing and control circuitry receives an address enable signal to initiate an access of the array whereby an address is received, decoded, and corresponding data retrieved or stored. Edge detection circuitry receives a memory clock and provides the address enable signal upon each rising edge and each falling edge of the memory clock to perform two memory operations in a single cycle of the memory clock. A memory operation includes addressing the memory and storing data in the memory or retrieving and latching data from the memory. In another form a double-rate dual port memory permits two independent read/write memory accesses in a single memory cycle.

摘要： A memory is written via data lines which are driven by a write driver. The data lines are coupled to a selected bit line pair as determined by a column address. The data lines are driven to a logic state representative of a data input signal by a write driver. The write driver is enabled during the presence of a write enable pulse. The write enable pulse is generated in response to a read mode to write mode transition and also in response to a transition of the data input signal. The data lines are precharged in response to a transition of the data input signal that occurs during the write mode.

摘要： A method for refreshing a Dynamic Random Access Memory (DRAM) includes performing a refresh on at least a portion of the DRAM at a first refresh rate, and performing a refresh on a second portion of the DRAM at a second refresh rate. The second portion includes one or more rows of the DRAM which do not meet a data retention criteria at the first refresh rate, and the second refresh rate is greater than the first refresh rate.
