Samsung recently announced what it says is the industry’s first 8Gb LPDDR4 Mobile DRAM chip. On the surface, that might not sound like much, but the new RAM actually may pave the way to allow Samsung to squeeze 4GB of RAM into the Galaxy S4.
“The 8Gb LPDDR4 is fabricated on 20-nanometer (nm) class process technology, and offers 1 gigabyte (GB) on a single die, which is the largest density available for DRAM components today,” the company said, noting that LPDDR4 offers a 50 percent performance jump over LPDDR3. The company could pack the Galaxy S5 with 4GB of RAM by using four of the 8Gb LPDDR4 die, each with 1GB of RAM. “With four of the 8Gb chips, a single 4GB LPDDR4 package can provide the highest level of performance available today,” Samsung boasted.
The Galaxy S5 is also expected to ship with a 64-bit processor, and earlier rumors have also pointed to a boost in RAM. In either case, Samsung is certainly paving the road so that one of its next phones can offer 4GB of RAM.
