Publication number: 20150074474Abstract: A device for repairing a memory device may include spare memory blocks that may replace corresponding memory blocks that include at least one non-operational memory cell. One or more registers may be coupled in a chain to store memory repair information. A memory repair module may identify, upon a power-up test of the memory device, non-operational memory cells, which are incremental to previously identified defective memory cells in previous power-up tests, and may provide corresponding memory repair information of the identified non-operational memory cells. A logic circuit may block access to one or more registers and may facilitate storing, in one or more unblocked registers, the corresponding memory repair information of the identified one or more non-operational memory cells. The memory repair module may swap a memory block including the identified non-operational memory cells with a spare memory block based on content of the one or more unblocked registers.Type: ApplicationFiled: September 27, 2013Publication date: March 12, 2015Applicant: BROADCOM CORPORATIONInventors: Mohammad Issa, Rakesh Kumar Kinger

Publication number: 20150071132Abstract: Embodiments of a four-port isolation module are presented herein. In an embodiment, the isolation module includes a step-up autotransformer comprising a first and second winding that are electrically coupled in series at a center node. The first port of the isolation module is configured to couple an antenna to a first end node of the series coupled windings. The second port of the isolation module is configured to couple a balancing network to a second end node of the series coupled windings. The third port is configured to couple a transmit path to the center node. The fourth port is configured to couple a differential receive path across the first end node and the second end node.

Patent number: 8976887Abstract: The system and method of the present disclosure exploit the fact that an undesired phase offset between signals up-converted and transmitted by transmitters of at least two transceivers is correlative with a phase offset between signals received and down-converted by receivers of the at least two transceivers. Such correlation occurs when the transmitter and receiver in each of the at least two transceivers share the same local oscillator and thus experience the same or very similar random phase noise. Using this fact, the system and method of the present disclosure are configured to measure the phase offset between signals received and down-converted by the receivers of the at least two transceivers and then use the measured phase offset to compensate for the phase offset between the signals up-converted by the transmitters of the at least two transceivers. This compensation allows MIMO communication, such as spatial multiplexing, to be better performed.Type: GrantFiled: June 14, 2013Date of Patent: March 10, 2015Assignee: Broadcom CorporationInventor: Ilan Reingold

Patent number: 8977126Abstract: Embodiments enable a network operator to use any (and a single) network management system (NMS) that it desires to manage a network having mixed fiber to the home optical network units (ONUs) and coaxial connected cable modems. For example, embodiments enable a cable company operator to use a DOCSIS (Data Over Cable Service Interface Specification) NMS (which the cable company already uses to manage its DOCSIS network) to manage such mixed network, by a simple addition of a DOCSIS Mediation Layer (DML) module between the NMS and the optical line terminal (OLT). On the other hand, embodiments enable a telephone company operator to use a standard EPON (Ethernet Passive Optical Network) OLT NMS with minor OLT and OAM (Operations, Administration, and Maintenance) protocol modifications to manage the same mixed network.Type: GrantFiled: June 30, 2011Date of Patent: March 10, 2015Assignee: Broadcom CorporationInventors: Edward Wayne Boyd, Ernie Bahm, Joel I.
