| 20090039927 | CLOCK MODE DETERMINATION IN A MEMORY SYSTEM - A clock mode configuration circuit for a memory device is described. A memory system includes any number of memory devices serially connected to each other, where each memory device receives a clock signal. The clock signal can be provided either in parallel to all the memory devices or serially from memory device to memory device through a common clock input. The clock mode configuration circuit in each memory device is set to a parallel mode for receiving the parallel clock signal, and to a serial mode for receiving a source synchronous clock signal from a prior memory device. Depending on the set operating mode, the data input circuits will be configured for the corresponding data signal format, and the corresponding clock input circuits will be either enabled or disabled. The parallel mode and the serial mode is set by sensing a voltage level of a reference voltage provided to each memory device. | 02-12-2009 |
| 20090316514 | Delay Locked Loop Implementation in a Synchronous Dynamic Random Access Memory - A clock applying circuit for a synchronous memory is comprised of a clock input for receiving a clock input signal, apparatus connected to the synchronous memory for receiving a driving clock signal, and a tapped delay line for receiving the clock input signal for delivering the clock driving signal to the synchronous memory in synchronism with but delayed from the clock input signal, the delay being a small fraction of the clock period of the clock input signal. | 12-24-2009 |
| 20100049870 | DENSE MODE CODING SCHEME - A lookup table for searching for a longest prefix match for a key is disclosed. The lookup table provides a match for a key in a single search cycle. The number of matches stored in the lookup table is maximized by storing each match in only one location in the lookup table. The binary tree is divided into a plurality of levels and each level has a plurality of subtrees. A subtree descriptor stored for a subtree includes a field for each node in the subtree. The state of the field indicates whether an entry for the node is stored in the table. The bit vector allows indexing of the single match stored for the key. | 02-25-2010 |
| 20100115172 | BRIDGE DEVICE HAVING A VIRTUAL PAGE BUFFER - A composite memory device including discrete memory devices and a bridge device for controlling the discrete memory devices. The bridge device has a virtual page buffer corresponding to each discrete memory device for storing read data from the discrete memory device, or write data from an external device. The virtual page buffer is configurable to have a size up to the maximum physical size of the page buffer of a discrete memory device. The page buffer is then logically divided into page segments, where each page segment corresponds in size to the configured virtual page buffer size. By storing read or write data in the virtual page buffer, both the discrete memory device and the external device can operate to provide or receive data at different data rates to maximize the performance of both devices. | 05-06-2010 |
| 20110050320 | USING INTERRUPTED THROUGH-SILICON-VIAS IN INTEGRATED CIRCUITS ADAPTED FOR STACKING - In an integrated circuit (IC) adapted for use in a stack of interconnected ICs, interrupted through-silicon-vias (TSVs) are provided in addition to uninterrupted TSVs. The interrupted TSVs provide signal paths other than common parallel paths between the ICs of the stack. This permits IC identification schemes and other functionalities to be implemented using TSVs, without requiring angular rotation of alternate ICs of the stack. | 03-03-2011 |

| 20120056335 | MULTI-CHIP PACKAGE WITH OFFSET DIE STACKING - A semiconductor device has a plurality of stacked semiconductor dice mounted on a substrate. Each die has similar dimensions. Each die has a first plurality of bonding pads arranged along a bonding edge of the die. A first group of the dice are mounted to the substrate with the bonding edge oriented in a first direction. A second group of the dice are mounted to the substrate with the bonding edge oriented in a second direction opposite the first direction. Each die is laterally offset in the second direction relative to the remaining dice by a respective lateral offset distance such that the bonding pads of each die are not disposed between the substrate and any portion of the remaining dice in a direction perpendicular to the substrate. A plurality of bonding wires connects the bonding pads to the substrate. A method of manufacturing a semiconductor device is also disclosed. | 03-08-2012 |
