Peripheral devices store data in non-volatile phase-change memory (PCM). PCM cells have alloy resistors with high-resistance amorphous states and low-resistance crystalline states. The peripheral device can be a Multi-Media Card/Secure Digital (MMC/SD) card. A PCM controller accesses PCM memory devices. Various routines that execute on a CPU in the PCM controller are activated in response to commands in the host-bus transactions. The PCM system increases the throughput of one or more phase-change memory devices by performing one or more of a read-ahead memory operation, a write-ahead memory write operation, a larger page memory write operation, a wider data bus memory write operation, a multi-channel concurrent multi-bank interleaving memory read or write operation, a write-cache memory write operation, and any combination thereof.

A multi-ring memory controller sends request packets to multiple rings of serial flash-memory chips. Each of the multiple rings has serial flash-memory chips with serial links in a uni-directional ring. Each serial flash-memory chip has a bypassing transceiver with a device ID checker that bypasses serial packets to a clock re-synchronizer and bypass logic for retransmission to the next device in the ring, or extracts the serial packet to the local device when an ID match occurs. Serial packets pass through all devices in the ring during one round-trip transaction from the controller. The average latency of one round is constant for all devices on the ring, reducing data-dependent performance, since the same packet latency occurs regardless of the data location on the ring. The serial links can be a Peripheral Component Interconnect (PCI) Express bus. Packets have modified-PCI-Express headers that define the packet type and data-payload length.

A restrictive multi-level-cell (MLC) flash memory prohibits regressive page-writes. When a regressive page-write is requested, an empty block having a low wear-level count is found, and data from the regressive page-write and data from pages stored in the old block are written to the empty block in page order. The old block is erased and recycled. A two-level look-up table is stored in volatile random-access memory (RAM). A logical page address from a host is divided by a modulo divider to generate a quotient and a remainder. The quotient is a logical block address that indexes a first-level look-up table to find a mapping entry with a physical block address that selects a row in a second-level look-up table. The remainder locates a column in the row in the second-level look-up table. If any page-valid bits above the column pointed to by the remainder are set, the write is regressive.

According to one embodiment of the invention, a method comprises receiving a write request for a file. A temporary file associated with the file is created in response to the write request. A write-lock is applied to the temporary file, namely the file includes a setting that restricts write access to only a component that created or opens the temporary file. Thereafter, the temporary file is closed to disable the write-lock and to enable a component that initiated the write request to access the temporary file.

A computing device is configured to make a determination as to whether a device is being held in a hand. In response to determining that the device is being held, the device transitions itself, or one or more of its hardware or software component, into a particular state of operation.

An entertainment system has a music storage system storing a plurality of music pieces, a playback system coupled with the music storage system, a navigation system providing current map information including a present location, wherein a current map has a plurality of zones each being assigned to one of a plurality of zone types, and a controller for controlling playback of selected music pieces, wherein the controller maintains a plurality of playlists, each having a plurality of music pieces and being assigned to at least one zone type. The controller receives information of a present location and a current zone type and selects an assigned playlist, wherein the navigation system further provides information about a distance and/or time to a next zone. The controller modifies the assigned playlist such that a transition to the next zone is timely synchronized with the ending of a music piece of the assigned playlist.

A method of fabricating a vertical MIM capacitor. An insulation layer is formed on the substrate. The insulation layer is patterned to form an opening in a predetermined area of a core electrode. Then, the opening is filled to form a sacrificial plug. Subsequently, the insulation layer is patterned to form a trench in a predetermined area of an outer electrode around the sacrificial plug. A fenced insulation layer is formed around the sacrificial plug simultaneously. After the sacrificial plug is removed, a metal layer is filled in the predetermined area of the core and outer electrodes. A vertical MIM capacitor comprising the core electrode, the fenced insulation layer, and the outer electrode is finally formed. The invention also provides a vertical MIM capacitor.
