A device and method for independent control of SDRAM memory in an SDRAM memory module. The device includes an in-line controller (ILC) coupled to receive indications of memory controller interrupt events. The ILC is coupled with the SDRAM memory, possibly through a registered buffer, in such a way that when an indication of a memory controller interrupt event is received, the ILC issues appropriate instructions to the SDRAM memory and prevents any spurious memory controller signals from being transmitted along the control bus. A memory module incorporating an ILC in communication with a memory controller and an SDRAM memory device or bank of such devices. Ultimately, a number of ILCs may be used, each controlling an individual SDRAM bank or discreet memory device. A method of protecting information stored on an SDRAM memory device, including the steps of providing an ILC in a SDRAM memory module receiving an indication of an interrupt event, interrupting the signals from the memory controller, if any, and providing instructions to the SDRAM memory device.

Independent in-line SDRAM control

An apparatus for programming flash based firmware is disclosed. The apparatus comprises a programmable control card (,) and a processor card (,). The programmable control card (,) includes a control card connector (,) and a programmable flash device (,). The processor card (,) includes a programming connector (,), a processor (,) and on-board flash devices (,). The control card (,) is operable to connect to the processor card (,) by connecting the control card connector (,) with the programming connector (,). Upon starting the processor card (,) control card (,) is operable to transfer programming code to the processor card (,).

Method and apparatus for initial programming of flash based firmware

A small broadband cross-connect system (10) includes a two-stage matrix (12) for processing and cross-connecting optical and electrical telecommunication network signals. An administration subsystem (14) provides centralized control and synchronization to the two-stage matrix (12). The two-stage matrix (12) may be expanded from 96 ports to 192 ports in a cost and space effective manner.
