In one embodiment, an electronic device comprises control circuitry. The control circuitry disables termination circuitry coupled to one or more input/output (I/O) signals of the electronic device during at least a portion of a relatively low frequency operation which causes insubstantial signal reflections at the I/O signals. The control circuitry re-enables the termination circuitry prior to the electronic device performing a relatively high frequency operation after completion of the low frequency operation, the high frequency operation causing substantial signal reflections at the I/O signals. The electronic device is a memory device in one embodiment. This way, the termination circuitry may be disabled during at least a portion of a refresh operation performed by the memory device and re-enabled prior to the memory device resuming normal operation (i.e., reads and writes) after completion of the refresh operation.

Method and apparatus for selectively disabling termination circuitry

A communications module that permits remote meter reading of a utility meter via a wireless modem that communicates using data packet networks along a communications system, such as ARDIS. The communications module is a microprocessor-based transmitter/receiver which receives data collection requests from a system server, initiates data collection from a utility meter, and reports the data back to a host computer system residing, for example, at a central office. Preferably, session-based communication using the meter protocol is implemented between the communications module and the meter, and packet switching is used between the communications server and the communications module through the network.

Wireless area network communications module for utility meters

A system and method for improving the delivery of data between a first signal transmitter/receiver device and a second signal transmitter/receiver device. Data is dynamically sized into at least one data packet having a data packet size that is no greater than an operational maximum data packet size capable of being transferred between the first wireless signal transmitter/receiver device and the second wireless signal transmitter/receiver device. At least one data packet is transferred from the first signal transmitter/receiver device to the second signal transmitter/receiver device until all data has been delivered.
