WebADVANTEST’s T5503HS system provides an optimal test solution for double-data-rate SDRAMs and other next-generation memory chips. The tester can operate at speeds up to 4.5 Gbps, fast enough to perform full-coverage testing of the most advanced memories. In addition, the system uses individual level settings, I/O dead-band canceling and WebGDDR5 and DDR4 memories use data bus inversion (DBI) coding to reduce termination power and decrease the number of output transitions. Two main strategies exist for encoding data using DBI: DBI DC minimizes the number of outputs transmitting a zero, while DBI AC minimizes the number of signal transitions. We show that neither of these … psychotherapy el pasoWebful DDR4 high-speed design will require the use of these new features and they should not be overlooked.
