Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. The memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. An error management provides reading and checking the copy after copying to the second portion. If the copy has excessive error bits, it is repeated in a different location either in the second or first portion. The reading and checking of the copy is accelerated by reading only a sample of it. The sample is selected from a subset of the copy having its own ECC and estimated to represent a worst error rate among the copy it is sampling. One embodiment has the sample taken from one bit of each multi-bit memory cell of a group.

Data errors in non-volatile memory inevitably increase with usage and with higher density of bits stored per cell. For acceptable quality assurance, conventional error correction codes (“ECC”) have to correct a maximum number of error bits up to the far tail end of a statistical population. The present memory is configured to have a first portion operating with less error but of lower density storage, and a second portion operating with a higher density but less robust storage. If excessive error bits (at the far tail-end) occur after writing a group of data to the second portion, the data is adaptively rewritten to the first portion which will produce less error bits. Preferably, the data is initially written to a cache also in the first portion to provide source data for any rewrites. Thus, a more efficient ECC not requiring to correcting for the far tail end can be used.

The error management is not started when a memory is new with little or no errors, but started after the memory has aged to a predetermined amount as determined by the number of erase / program cycling its has experienced.

A semiconductor device having a two-layer well structure and a small margin required at the boundary of a well region and comprising a substrate-bias variable transistor and a DTMOS. Field effect transistors (223) are formed on a P-type shallow well region (212). The depth of a shallow device isolation region (214) on the P-type shallow well region (212) is less than the depth of the junction between an N-type deep well region (227) and the P-type shallow well region (212).

A method is presented for idle speed control of a lean burn spark ignition internal combustion engine using a fuel-based control strategy. In particular, the idle speed control strategy involves using a combination of fuel quantity or timing and ignition timing to achieve desired engine speed or torque while maintaining the air / fuel ratio more lean than prior art systems. Depending on engine operating conditions, the fuel quantity or timing is adjusted to give a more rich air / fuel ratio in order to respond to an engine speed or torque demand increase. Additionally, due to operation close to the lean misfire limit, the spark ignition timing is adjusted away from MBT in response to an engine speed or torque demand decrease. The advantages of this fuel based control system include better fuel economy as well as fast engine response time due to the use of fuel quantity or timing and ignition timing to control engine output.

A method for manufacturing an optical disc and a method for transporting a multi-layered optical disc are provided. When adhering the sheet and the disc substrate, after the adhesive is supplied to the outer side of the groove on the disc substrate, the sheet is loaded on the disc substrate.

The bitrate control of known video encoders is based on a control of the quantization step size per picture block. In transform coding of relatively large picture blocks, the video picture comprises a too small number of picture blocks to obtain a desired number of bits per picture. In conformity with the invention, the target value for the number of bits per picture block is divided into N sub-targets (Rt(k,n)). The series of coefficients of a picture block is divided into N segments (L(n)) with reference to an estimation for the cumulative distribution 20 of the bit cost per picture block. The quantization step size is subsequently adapted per segment to the corresponding sub-target. Since the number of segments is N times larger than the number of picture blocks, an accurate bitrate control is possible. If desired, the estimation for the cumulative distribution is adapted from picture to picture.
