The extension time for continuing the primary constant-current charging is preferably set so as to be shorter as the battery temperature is higher. Also a secondary charging time for executing the secondary constant-current charging is preferably set so as to be shorter as the battery temperature is higher.

Title: Turbo code symbol interleaver
Inventor: WEI LEE-FANG
IPC: H03M13/25
Filed: 2000-05-22
Granted: 2002-03-01
Abstract: Advantageous error rate performance, high bandwidth efficiency, low delay and reduced error floor are achieved at an acceptable level of decoding complexity via the use of serial concatenated turbo codes. These are codes for which at least some of the output bits, including at least one redundant bit, provided by a first, outer encoder are, after interleaving, further processed by a second, inner encoder. The interleaver uses as its interleaved elements the bits associated with a particular symbol interval. The resulting data and redundant bits then select a symbol from a predetermined constellation for transmission. In the receiver, the turbo code is decoded using a corresponding number of soft output decoders which operates iteratively in such a way that improved performance as compared to a single encoding can be achieved. The turbo codes can be of various dimensionalities and can be used as a component of a multilevel code to achieve a desired level of bandwidth efficiency.

Title: Voltage regulation for integrated circuit memory
Inventor: CHEN CHUN
IPC: H01L27/115
Filed: 2000-08-15
Granted: 2001-09-21
Abstract: An integrated circuit has an improved voltage regulator for use with memory devices that utilize secondary electron injection for programming. The memory device, typically a floating-gate EEPROM, has source and drain regions formed in a doped tub region. A first voltage source is used to reverse-bias a diode, formed in the same process as the source and drain regions of the memory device, to near the breakdown voltage. A small bias current flows through the reverse-biased diode from the first voltage source to a second voltage source, thereby establishing a reference voltage. The drain voltage of the memory device is then biased, typically by a bipolar transistor, to about a diode drop (about 0.7V) below the reference voltage, and hence correspondingly below the drain-to-tub breakdown voltage of the memory device. In this manner, the reference voltage tracks changes in the memory device due to process variations, temperature variations, etc., so that improved programming speed and/or disturb margins are obtained.
