Samsung today announced a new memory chip for smartphones, tablets, and laptops. The module is an 8Gb, low power double data rate 4 (LPDDR4) DRAM chip on a single 1GB die.
It is fabricated with a 20nm processes. According to Samsung, four can be combined together to form a single 4GB RAM module. The 8Gb LPDDR4 DRAM chip uses a Low Voltage Swing Terminated Logic (LVSTL) I/O interface. Samsung says this enables data transfer rates of 3.2Gbps per pin, which is twice the speed of today’s LPDDR3 DRAM modules.
Samsung claims its new chip offers 50% higher performance, but uses 40% less energy, making it ideal for high-end UHD smartphones and tablets. The chip will reach volume production next year.
