抜粋

A retention analysis method for ferroelectric random access memory (FeRAM) was developed, in which read signal voltages from memory cells are measured. The method uses on-chip sample/hold circuits, an off-chip A/D converter, and memory largescale integration testing equipment. FeRAM chip retention lifetime can be estimated on the basis of FeRAM read signal voltages after retention periods of one day and up. When used as a tool to estimate long-term data retention in FeRAM chips and to analyze fluctuations in memory cell characteristics, this method can provide useful information about FeRAM reliability.
