Abstract
An integrated circuit with a flexible data strobe signal (DQS) bus structure is presented. The integrated circuit has a number of input/output (I/O) modules with a number of data pins to receive and transmit data. In addition, a subset of the I/O modules also have a data strobe pin. The input/output modules are connected to data strobe signal buses having a fixed configuration. The configuration of the fixed DQS bus groups a number of data pins with a corresponding data strobe pin and the grouping of data pin spans multiple I/O modules. The integrated circuit also has a flexible data bus connected to the I/O modules. Data pins of I/O modules of a second integrated circuit are mapped a subset of the data pins of corresponding I/O modules of the integrated circuit. The flexible data strobe signal bus enables selection of the subset of data pins in the integrated circuit.
