A semiconductor memory device including an array of memory cells. The memory device includes a first output driver coupled to a first output terminal, and a second output driver coupled to a second output terminal. The memory device further includes a voltage divider coupled between the first and second output terminals, to generate a control voltage based on a voltage level present on the first output terminal and a voltage level present on the second output terminal. The memory device further includes a comparator, coupled to the voltage divider, to compare the control voltage with a reference voltage, wherein an amount of voltage swing of the first output driver is adjusted based on the comparison between the control voltage and the reference voltage.

Semiconductor memory device having a controlled output driver characteristic

A memory device has interface circuitry and a memory core which make up the stages of a pipeline, each stage being a step in a universal sequence associated with the memory core. The memory device has a plurality of operation units such as precharge, sense, read and write, which handle the primitive operations of the memory core to which the operation units are coupled. The memory device further includes a plurality of transport units configured to obtain information from external connections specifying an operation for one of the operation units and to transfer data between the memory core and the external connections. The transport units operate concurrently with the operation units as added stages to the pipeline, thereby creating a memory device which operates at high throughput and with low service times under the memory reference stream of common applications.
