Online write-up method and device of M2M chip

Abstract

The invention discloses an online write-up method and device of an M2M chip. The write-up method comprises the steps of transferring a failed chip from a chip write-in device into a waste chip box through a chip moving device while detecting that the failed chip is written in the chip write-in device; writing up the data corresponding to the failed chip to a new chip through the chip write-in device, wherein the chip moving device sequentially transfers other written-in chip to corresponding positions on a carrier belt while the position corresponding to the failed chip is reserved during thewrite-up process; moving the carrier belt after transferring one or a plurality of written-in chips to the carrier belt; and moving the new chip to the reserved corresponding position on the carrier belt through the chip moving device after the new chip is written up. With the adoption of the online write-up method and device of the M2M chip, the device stop time can be effectively reduced; the device fault rate can be reduced; and the yield can be increased.

Description

technical field [0001] The invention relates to the technical field of chip manufacturing, and in particular provides an online rewriting method and a rewriting device for an M2M chip. Background technique [0002] With the development of science and technology, more and more devices need to communicate and network. The emergence and development of communication network technology has brought great changes to the social life. People can communicate more quickly and exchange information more smoothly. But at present, only computers and some other IT devices have such communication and network capabilities. Numerous ordinary machines and equipment have almost no networking and communication capabilities, such as industrial equipment, instrumentation, home appliances, vehicles, vending machines, factory equipment, etc. The goal of M2M technology is to enable all machines and equipment to have networking and communication capabilities, and its core concept is Network Everythi...
