A method, apparatus and system for reducing memory latency is disclosed. In one embodiment, data between a host computer system and a memory is communicated via a port or a group of ports at the memory over multiple time intervals, wherein the host computer is coupled to the memory. Further, a command associated with the data is communicated between the host computer system and the memory via the port or the group of ports over a single time interval.

Method and system for improving serial port memory communication latency and reliability

Embodiments relate to half-duplex bidirectional transmission of data compliant with a first standard (e.g., Universal Serial Bus (USB) standard) over a physical channel of a multimedia link for transmitting audio/video ('A/V') data compliant with a second standard (e.g., Mobile High-Definition Link (MHL) standard) between a source device and a sink device using time division multiplexing (TDM). The source device sends units of data including A/V data and forward data compliant with the first standard at first times whereas the sink device sends units of data including backward data compliant with the first standard at second times between transmissions from the source device. The first times do not overlap with the second times. Synchronization signals may be added to the first and second units of data to align character symbols embedded in the first and second units of data.

A method and system for inter-port communication utilizing a multi-port memory device. The memory device contains an interrupt register, an interrupt signal interface (e.g., a dedicated pin), an interrupt mask, and one or more message buffers associated with each port. When a first component coupled to a first port of the memory device wants to communicate with a second component coupled to a second port of the memory device, the first component writes a message to a message buffer associated with the second port. An interrupt in the input register of the second port is set to notify the second component coupled to the second port that a new message is available. Upon receiving the interrupt, the second component reads the interrupt register to determine the nature of the interrupt. The second component then reads the message from the message buffer.
