As the integrated circuit technology develops to the deep sub-micron field, memory storage node is more susceptible to the influence of space radiation particles, causing the data in memory upset more easily. Memory unit size decreased makes one die can be placed more memory units, so the distance between the memory units decreased and the

As most important part of digital circuit system, the Memory IC need be tested very rigorous during production. Different memory type has different structure and different working module, need different test methodology. All test items are produced by test program, so we need test program has good test coverage while continues reduce test time, improve

A new security technology for memory element is presented in this paper. It is well known that, memory element is highly sensitive, and when it falls into the ground, maybe the datas saved in the memory element will be wrong or lost. Acceleration sensor has the function to be aware of the change of the
