    Sounds like a very powerful improvement. There's so much that can be expanded upon, while keeping a solid battery life with this. Instead of the generally average or poor battery life of some products, especially under a really heavy use during the day to day tasks.

    Looking forward to this being a reality in new products to come. It might actually interest me in something, with some actual battery life that won't seem absolutely terrible.

    You know there would be longer battery life, if manufacturers quit packaging smaller batteries when their devices use less power. I am personally not interested in any device, that will not stay charged over a period of 24 hours usage.

    Hold on... aren't static RAM modules extremely expensive for large capacities due to the "large" area and amount of transistors they need per bit? That's the reason why SRAM is used for cache and small, fast access memories; for bigger capacities like 2 GB DRAM fits better, needing just 1 transistor per bit and its parasite capacitor and a refresh circuit.

    SRAM is more adecuate for small buffers, cache memory and some aid for the bigger and cheaper DRAM. Both volatile but just one of them needing refresh circuits. John Hennessy's computer architecture book back-ups me, not Wikipedia --even my former computer architecture teacher who works at Intel and gave us a more accurate current cost of the SRAM per MB, don't remember the exact amount [it was last semester] but it would cost thousands of dollars to manufacture SRAM in the order of GB.

    It is a pity that Toshiba do not make phones to immediately utilise this tech advancement...
