This week, we reported about the release of interesting memory type DDR3L-RS, which provided almost simultaneously the company Micron ( 30-nm ) and Hynix ( 20 nm ).
Let's start with how DDR3L-RS memory is positioned . Theoretically, since the mobile platform Haswell, which is especially important for ultrabooks, in the PC promises to appear memory type LPDDR3 . At the same time, LPDDR3 memory raise the price of the system, which runs counter Intel desire to steadily reduce the base ultrabook cost . As a compromise to balance the cost, power consumption and capacity of main memory can be a choice of memory manufacturers DDR3L-RS.
Micron Estimated, cost of chips DDR3L-RS will be 20% more than DDR3L. The latter, in turn, only 10% more pervasive than DDR3 memory. LPDDR3 Memory will steadily remain expensive for quite some time, as demand for smartphones and tablets will not leave surplus for the computer market.
Thus, the DDR3L-RS memory will be more expensive than DDR3 by about 30%, but its more economical. By how much? In idle mode DDR3L-RS memory system will save up to 25% energy, according Micron. In working state DDR3L-RS memory will consume as much as DDR3 memory.
Based on measurements of its temperature, cooled down in idle mode and 45 degrees Celsius memory DDR3L-RS reduces the intensity of updating data and, as a result, the value of current IDD6 (self-refresh). Through DDR3L-RS memory is saving energy . Cold crystals do not require such intensive regeneration cycle, as hot as the current DDR3 standard requires the update mode for 85 degrees, which can be observed in practice, not always. Clearly, the gain from using DDR3L-RS will give a significant effect only in the case of mobile systems. Related Products :
