The invention relates to a fast reading device of a phase change memory, which comprises a phase change memory cell to be read, a charging circuit, an overshoot recovery rate detecting circuit, a sensitive amplifier circuit and a reference level or a reference memory cell. On one hand, the phase change memory cell (which can be abstracted as a resistor in the circuit) and a parasitic capacitor ona digit line form a resistor-capacitor (RC) circuit, and on the other hand, a gated metal oxide semiconductor (MOS) pipe instantly enters a linear region from a saturation region when being switched on/of, thereby causing an overshoot phenomenon. For phase change resistors of different states, the corresponding recovery rates after the overshoot are different. By reading the recovery rate of the digit-line level after the overshoot and fast reading the state of the phase change memory cell, the reading rate of the whole memory is accelerated. In addition, fast reading is beneficial to avoiding the damage caused by reading operation to the phase change cell, thereby achieving the purpose of reducing reading interference.

A method and system for reading various codes such as codes imprinted on an item includes a first and a second code reader each scan the code on the item to read the code. The data obtained by the first and the second code reader is merged to reconstruct the code on said item. The position of the one or more of the code readers may be adjusted such that the maximum reading efficiency of said code by each code reader occurs at different points of the scanned code. This helps to facilitate merging the data obtained by the first and the second code reader to reconstruct the code on the item. By adjusting the position of one or more of the code readers, degradation of the reading of the item code due, for example, to beat frequencies occurs at different points in the code for each code reader. The method and system may be employed in various applications such as with sortation systems and other paper handling equipment. The method and system may be employed with different types of codes including various forms of bar codes. The item may have single or plural codes, which may be the same or different type codes.

An optical disk drive which increases a read rate when a read command from a host system is input. Data read from the optical disk drive are buffered in cache memory, and requested data are subsequently transferred to a host system. The cache memory is divided into cache A and cache B. Directory data are chiefly buffered in the cache A, and file data are chiefly buffered in the cache B. A cache hit rate achieved when the directory data and the file data are alternately read is improved.

A method and system are disclosed for ejecting ink drops from a plurality of ink jet nozzles in order to print on an envelope in a mail piece production process. The envelope has been stuffed and is therefore not flat, especially near the edges.
