[MEMO] Preliminary Data Sheet E0034N10 13 [MEMO] 14 Preliminary Data Sheet E0034N10 NOTES FOR CMOS DEVICES 1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS Note: Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to V DD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function. Preliminary Data Sheet E0034N10 15 CAUTION FOR HANDLING MEMORY MODULES When handling or inserting memory modules, be sure not to touch any components on the modules, such as the memory IC, chip capacitors and chip resistors. It is necessary to avoid undue mechanical stress on these components to prevent damaging them. When re-packing memory modules, be sure the modules are NOT touching each other. Modules in contact with other modules may cause excessive mechanical stress, which may damage the modules. • The information in this document is current as of June, 2000. The information is subject to change without notice. For actual design-in, refer to the latest publications of Elpida's data sheets or data books, etc., for the most up-to-date specifications of Elpida semiconductor products. Not all products and/or types are available in every country. Please check with an Elpida Memory, Inc. for availability and additional information. • No part of this document may be copied or reproduced in any form or by any means without prior written consent of Elpida. Elpida assumes no responsibility for any errors that may appear in this document. • Elpida does not assume any liability for infringement of patents, copyrights or other intellectual property rights of third parties by or arising from the use of Elpida semiconductor products listed in this document or any other liability arising from the use of such products. No license, express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of Elpida or others. • Descriptions of circuits, software and other related information in this document are provided for illustrative purposes in semiconductor product operation and application examples. The incorporation of these circuits, software and information in the design of customer's equipment shall be done under the full responsibility of customer. Elpida assumes no responsibility for any losses incurred by customers or third parties arising from the use of these circuits, software and information. • While Elpida endeavours to enhance the quality, reliability and safety of Elpida semiconductor products, customers agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize risks of damage to property or injury (including death) to persons arising from defects in Elpida semiconductor products, customers must incorporate sufficient safety measures in their design, such as redundancy, fire-containment, and anti-failure features. • Elpida semiconductor products are classified into the following three quality grades: "Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products developed based on a customer-designated "quality assurance program" for a specific application. The recommended applications of a semiconductor product depend on its quality grade, as indicated below. Customers must check the quality grade of each semiconductor product before using it in a particular application. "Standard": Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots "Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) "Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems and medical equipment for life support, etc. The quality grade of Elpida semiconductor products is "Standard" unless otherwise expressly specified in Elpida's data sheets or data books, etc. If customers wish to use Elpida semiconductor products in applications not intended by Elpida, they must contact an Elpida Memory, Inc. in advance to determine Elpida's willingness to support a given application. (Note) (1) "Elpida" as used in this statement means Elpida Memory, Inc. and also includes its majority-owned subsidiaries. (2) "Elpida semiconductor products" means any semiconductor product developed or manufactured by or for Elpida (as defined above). M8E 00. 4
