In prior renditions of synchronous DRAM such as SDRAM, DDR and DDR2, JEDEC pushed hard on speed without worrying too much about power, said Jim Handy, director of Objective Analysis. With DDR3 and LPDDR3, JEDEC worked to bring the power specifications back down while continuing to increase speed.
But adoption typically depends on other parts of the system, Handy said. For cell phones it's less sudden than it is in PCs, where a single supplier dictates which interface the chipsets are going to support. But the power advantage is a sufficiently compelling reason for device makers to quickly switch over to LPDDR3.
"I would anticipate a quick conversion of cell phones to LPDDR3. In tablets, so far Apple is the only supplier of any significance, so adoption depends solely on their moves," Handy said.
It's hard to predict when Samsung will ramp up production of LPDDR3, Handy said.
"Samsung has announced products lately that don't show up in production systems for over a year," Handy said.
