G11C 5/14

US Classification:

365226, 365200, 36523005

Abstract:

A system and method of providing a voltage to a non-volatile memory. The system includes an output pin to provide an output voltage to a non-volatile memory and includes a memory to store a table. The table includes a plurality of operating voltage levels. The system further includes a voltage mode module to apply a first voltage at a first of the plurality of operating voltage levels at the output pin prior to a read operation on the non-volatile memory. The voltage mode module applies a second voltage at a second of the plurality of voltage levels at the output pin in response to a read operation that returns a failure condition.

Abstract:

A multiple access wireless communications architecture provides selective, simultaneous communications with wireless devices located in different sections of a spatial area around a communications apparatus referred to as “sectors”. This includes communications between wireless devices in a single sector, between wireless devices in different sectors and between wireless devices and a wired network or wireless backhaul network. The wireless communications architecture generally includes two or more wireless antenna arrangements that are each configured to provide communications with wireless devices located in a particular sector. Each wireless antenna arrangement is further configured to determine whether signals are being communicated on a communications channel before transmitting on the communications channel. This may be implemented, for example, using a carrier sense or energy detection mechanism. Wireless devices within a sector may communicate on the same or different communications channels, depending upon the particular multiple access protocol employed.

US Classification:

713 1, 714 1, 711154, 711162

Abstract:

A memory device has a plurality of memory blocks utilized to store data. One of the blocks is used as a hidden memory block to store an operating system program, instead of data. The hidden memory block is designated as a bad block so that data will not be written into the hidden memory block, but a tag associated with the hidden memory block identifies that the hidden memory block contains the operating system program.

International Classification:

H04B 10/00

US Classification:

398106, 398107, 398128, 398135, 398138

Abstract:

An Infrared (IR) receiver includes a programmable decoder having a normal mode of operation and a proprietary mode of operation. When the programmable decoder is in the normal mode of operation, the programmable decoder decodes frames of an IR data transmission to produce decoded data. When the programmable decoder is in the proprietary mode of operation, the programmable decoder passes data of the IR data transmission during a time out period to produce raw data. The IR receiver also includes a pulse detection circuit that generates a pulse detection signal in response to detecting the IR data transmission. The IR receiver further includes a timer circuit that generates the timeout period in response to the pulse detection signal.

US Classification:

711165, 711103, 711170, 717168

Abstract:

An instruction set is executed from Read Only Memory (ROM). When a current instruction in the instruction set corresponds to a reserved patch memory block of ROM, a Random Access Memory (RAM) index and a ROM return address are loaded into a memory map, and a program counter is set to a first reserved ROM address. After jumping the program counter to the first reserved ROM address, the program counter is jumped to RAM based on the RAM index to execute a patch code, which includes at least one instruction to set the program counter to a second reserved ROM address. When the program counter equals the second reserved ROM address, the ROM return address is retrieved. Then the instruction set is executed from ROM based on the ROM return address.

International Classification:

H04B 10/06

US Classification:

398202

Abstract:

An infrared data receiver includes an infrared detector for generating a received signal from an infrared input signal. A sampling module generates a sequence of sampled data from the received signal. A plurality of processing modules are included, wherein each processing module is capable of detecting and decoding data in at least one of a plurality of data formats. Each processing module analyzes the sequence of sampled data for its particular data formats. When a processing module detects one of its data formats, it generates a detection signal and decodes the sequence of sampled data into decoded data. A controller module receives the detection signal from one of the plurality of processing module, and disables the other ones of the plurality processing modules.
