发明名称 METHOD AND APPARATUS FOR REPEATABLE DRIVE STRENGTH ASSESSMENTS OF HIGH SPEED MEMORY DIMMS
摘要 The present invention assesses memory (DIMM) strength by calculating frequency content of a radiated field which is collected by an apparatus, such as a dipole antenna. Radiated field is created by accelerated charge, which is a function of the slew rate or DIMM strength. Radiated power is directly proportional to the frequency at which bits are driven. By separating the radiated field from the near field or stored field, the DIMM strength content is isolated from other functional DIMM issues, such as tRCD latency, refresh cycles, addressing mode, etc. By examining the radiated power, the disadvantages of the prior art, such as by probing the DIMM's contacts, are avoided.
