The object of the IEC is to promote international co-oper
13、ation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt wi
14、th may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined
15、by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees.
16、3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake
17、 to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. 5) The IEC provides no marking procedure
18、to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. The IEC shall not be held respo
19、nsible for identifying any or all such patent rights. International Standard IEC 60748-2-11 has been prepared by subcommittee47A: Integrated circuits, of IEC technical committee47: Semiconductor devices. This standard is a blank detail specification for single supply integrated circuit electrically
20、erasable and programmable read-only memory. The text of this standard is based on the following documents: Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The QC number that appears on the front cover of this publica
21、tion is the specification number in the IEC Quality Assessment System for Electronic Components (IECQ).

22、he statutes of the IEC and under the authority of the IEC. The object of this system is to define quality assessment procedures in such a manner that electronic components released by one participating country as conforming with the requirements of an applicable specification are equally acceptable
23、in all other participating countries without the need for further testing. This blank detail specification is one of a series of blank detail specifications for semiconductor devices and shall be used with the following IEC publications: IEC 60747-10/QC 700000:1991, Semiconductor devices Part10: Gen
