摘要:
A memory system including a memory controller with channel interfaces connecting memory groups via channels. Each channel interface communicates control, address and/or data (CAD) signals to a channel-connected memory group synchronously with a slave clock derived from an input clock. The various slave clocks being uniquely generated by application of channel interface specific phase/frequency modulation or temporal delay, such that the respective CAD signals are characterized by skewed transition timing.
摘要:
A method of interfacing a memory controller and a memory device in a memory system includes transmitting a control signal between the memory controller and the memory device using a time division multiplexing (TDM) communication process, and transmitting data between the memory controller and the memory device using a serializer/deserializer (SERDES) communication process. Data communication in the memory system is performed via a physical channel and a plurality of virtual channels corresponding to the physical channel.

Disclosed is a thermorod capable of actively releasing drugs according to temperature of the thermorod and a method of manufacturing the same. The thermorod generates heat by eddy current loss and hysteresis loss in an induced magnetic field. The thermorods can effectively administer drugs, such as anti-cancer drugs, since the thermorods may be used to perform local hyperthermia at 36.5° C. or above and to actively control the active drug release and delivery according to temperature as well. The thermorods may be useful in the treatment of resting tumor cells along with hyperthermia by performing a surgical operation on lesion sites of biological tissues. Using the thermorod, the drug is effectively delivered to an affected part in response to the active drug release. This can minimize the toxicity caused by an increase in blood drug concentration, which occurs when a drug is administered by a conventional method.

The present invention provides novel photopolymers for use in liquid crystal display. The photopolymers are cinnamate-containing photopolymers wherein a mesogen, preferably containing a benzene ring, is introduced between a polyvinyl main chain and a cinnamate group, and also wherein the cinnamate group can be substituted with a cyanide group, an alkyl group, a halogen atom or a fluorocarbonyl group. The cinnamate-containing photopolymers have improved stability and photoelectric properties, and improved pre-tilt angle. The photopolymers can be used to form an orientation film for an LCD in a non-rubbing process, and can be used alone or with a cross linking agent.
