    摘要: The read latency of a plurality of memory devices in a high speed synchronous memory subsystem is equalized through the use of at least one flag signal. The flag signal has equivalent signal propagation characteristics read clock signal, thereby automatically compensating for the effect of signal propagation. After detecting the flag signal, a memory device will begin outputting data associated with a previously received read command in a predetermined number of clock cycles. For each of the flag signal, the memory controller, at system initialization, determines the required delay between issuing a read command and issuing the flag signal to equalize the system read latencies. The delay(s) are then applied to read transactions during regular operation of the memory system.

    摘要: In a high speed memory subsystem differences in each memory device's minimum device read latency and differences in signal propagation time between the memory device and the memory controller can result in widely varying system read latencies. The present invention equalizes the system read latencies of every memory device in a high speed memory system by comparing the differences in system read latencies of each device and then operating each memory device with a device system read latency which causes every device to exhibit the same system read latency.

    摘要: A system and method for decoding command signals that includes a command decoder configured to generate internal control signals to perform an operation based on the command signals and an operating state. The same combination of command signals can request different commands depending on the operating state. A command is selected from a first set of operations according to the command signals when the memory system is in a first operating state and a command is selected from a second set of operations according to the command signals when the memory system is in a second operating state.

    摘要: A method and apparatus for active termination control of a memory module is disclosed. A memory controller provides a single active termination control line per memory module which is used to control memory devices on both sides of a module. The active termination control signal is active for all write functions to the memory devices on the modules. A device read signal generated by the memory devices on one side of the module disables the active termination control signal for memory devices on both sides of the module to enable faster turnarounds between write and read operations.
