Abstract: An apparatus and method providing independent control of on-die termination (ODT) of output buffers. The ODTs for the buffer circuits of an input/output (I/O) buffer can be enabled and disabled in response to an ODT control signal. Additionally, the ODTs for a first set of the buffer circuits can be enabled and disabled responsive to the ODT control signal and the ODT for at least one of a second set of the buffer circuits is disabled.

Abstract: A circuit and method for providing temperature data indicative of a temperature measured by a temperature sensor. The circuit is coupled to the temperature sensor and configured to identify for a coarse temperature range one of a plurality of fine temperature ranges corresponding to the temperature measured by the temperature sensor and generate temperature data that is provided on an asynchronous output data path.

Abstract: A synchronous dynamic random access memory (“SDRAM”) device includes several banks of memory cell coupled to a read data path and a write data path. The read data path includes a read latch that stores a relatively large number of read data bits received in parallel from a bank of memory cells. Groups of the stored read data bits are sequentially selected by a multiplexer and applied to a read data bus. Groups of write data bits are sequentially coupled to the SDRAM device through a write data bus that is separate from the read data bus, and they are sequentially stored in input registers. When the input registers are full, the write data bits are coupled in parallel to a bank of memory cells. The number of bits in the write data bus is preferably a submultiple of the number of bits in the read data bus.

Abstract: A method of selecting CAS latencies in a system. Specifically, a system which includes a plurality of memory devices and a memory controller is provided. Because different memory devices may have different CAS latencies, a system CAS latency is selected wherein the system CAS latency is the fastest common CAS latency of each of the plurality of memory devices. After a read request is delivered to a memory device, the memory controller initiates a transmission flag to the memory device at a time equal to the system CAS latency, indicating that it is safe to transmit the requested data from the memory device to the memory controller. The transmission flags may be used in conjunction with mode registers such that one or both of the transmission flag and the data may be received by or delivered by a corresponding memory device.
