The invention discloses a failure mode analysis
system and method applied to a
DRAM (
Dynamic Random Access Memory), and relates to the technical field of semiconductors. The method comprises the steps of obtaining test resources by preparing a test environment; carrying out a
frequency reduction test on the
DRAM chip and the circuit board with problems, observing whether the
DRAM chip and the circuit board are improved or not, and if the
DRAM chip and the circuit board are improved, carrying out
adaptation through soft modification or hard modification; if the
frequency reduction test is not improved,
signal integrity measurement is carried out, possible
signal problems are searched, and the compatibility problem is solved by adjusting
time sequence parameters; performing a special configuration test, verifying the influence of the special configuration, and performing
adaptation according to a test result; and carrying out compatibility
adaptation through soft modification or hard modification according to the test result. According to the method, the reasons of the adaptation compatibility failure can be quickly and effectively found, the adaptation problem is improved, the
verification analysis time occupied by anomaly analysis is greatly shortened, and the matching degree of compatibility adaptation of the
DRAM chip and the SOC platform on the market is improved.
