A memory device driver is described that can support multiple differing memory devices, in particular, differing Flash memory devices, by being internally re-configurable to match the driving and management requirements of the particular memory device. This allows for a limited number of operating system versions to be produced and maintained for a given system by the manufacturer, reducing the possibility of misconfiguration of the system/device by the inadvertent updating or programming of the wrong operating system version by an end user or service personnel. The resulting driver routine and/or operating system is also typically smaller than operating systems/drivers that compile in or load multiple separate drivers into themselves. In one embodiment of the present invention, the software driver is automatically configures itself by querying the memory device for a device ID and/or manufacturer code or by detecting a specific characteristic of the memory device being driven.

Runtime flash device detection and configuration for flash data management software

A device manager receives an operation request for a memory device. The device manager suspends interrupts to be serviced and determines if there is sufficient time available to perform the requested operation. If there is sufficient time available and the device manager is in an exclusive mode, the state of the memory device is checked to determine if it is currently executing an operation. If so, this operation is suspended and the requested operation is issued to the memory device. The device manager polls the memory device to determine when the requested operation has been completed. Upon completion, the interrupts are re-enabled and control of the memory device is returned to the system.

Method for reading while writing to a single partition flash memory

A system includes a circuit board module having a device mounting section. The system further includes a small form factor transceiver and a form factor converter. The form factor converter is configured to concurrently connect to (i) the circuit board module and (ii) the small form factor transceiver. The form factor converter includes an exterior portion defining a large form factor (e.g., the standard X2 form factor) to fit within the device mounting section of the circuit board module when the form factor converter connects to the circuit board module, and an interior portion defining a small form factor (e.g., the standard SFP form factor) location to receive at least a portion of the small form factor transceiver when the form factor converter connects to the small form factor transceiver.

Repeater module

A repeater, useable for connecting switches in a data communication network, is provided in a distributed and/or modular fashion. The repeater includes a plurality of separate and distinct components or modules connected to or at least partially housed in, the various switches which the repeater modules couple. The distributed and/or modular repeater facilitates accommodating various switching or repeater needs as a network grows or contracts. A light pipe, preferably integral with a module case, conveys indicator lights to a position visible when viewing a switch front panel. A heat spreader unit receives and/or conveys heat and/or protects against undue EMI. A collision-handling state machine transmits modified collision fragments so as to avoid reduction in interpacket gaps, e.g. by downstream repeater modules.
