    Samsung has developed a new technology for nonvolatile memory which surpasses all current technologies.

    The Korean company announced that it has completed the first working prototype of what is expected to be the main memory device to replace high density NOR flash within the next decade.

    The Phase-change Random Access Memory (PRAM) is more scalable than any other memory architecture being researched and features the fast processing speed of RAM for its operating functions combined with the non-volatile features of flash memory for storage.

    A key advantage in PRAM is its extremely fast performance. Because PRAM can rewrite data without having to first erase data previously accumulated, it is effectively 30-times faster than conventional flash memory. Incredibly durable, PRAM is also expected to have at least 10-times the life span of flash memory.

    PRAM will be a highly competitive choice over NOR flash, available beginning sometime in 2008. Samsung designed the cell size of its PRAM to be only half the size of NOR flash. Moreover, it requires 20 percent fewer process steps to produce than those used in the manufacturing of NOR flash memory.

    Samsung’s new PRAM was developed by adopting the use of vertical diodes with the three–dimensional transistor structure that it now uses to produce DRAM. The new PRAM has the smallest 0.0467um 2 cell size of any working memory that is free of inter-cell noise, allowing virtually unlimited scalability.
    Adoption of PRAM is expected to be especially popular in the future designs of multi-function handsets and for other mobile applications, where faster speeds translate into immediately noticeable boosts in performance. High-density versions will be produced first, starting with 512 Mb.

    Desculpem a ignorância, mas não havia um tipo de memória com este nome nos Macintosh antigos?

    Optimo, desejo uma morte rapida aos discos mecânicos.

    S1nnless What is folding?

    x2. Ou que a Intel comece a usar aquela tecnologia que usa memória Flash para aumentar o desempenho

    A PRAM (Parameter RAM) era o equivalente à RAM da BIOS de um IBM-PC Compativel mas muito mais versatil.

    Que venham as pRAM :002:

    isto quer dizer que morre. Ou seja, não dá para usar como disco rigido... Pelo menos para pessoas que o estão sempre a usar.

    Se dura 10x mais que a flash actual é capaz de durar bem mais que os discos rígidos...

    Quantas vezes se pode gravar algo pra uma flash actual?

    x10... parece-me bem :D
     
  12. Uma curiosidade: qual as caracteristicas da NOR flash? De onde vem o prefixo "NOR"?

    O NOR tem a haver com a logica, e é uma junção do Not e do Or (pensso que é assim)

    As caracteristicas ja nao sei
     
  14. :wvsore: Sim, por acaso essa informação já sabia. A porta NOR tem apenas a sua saida com valor lógico 1 se as suas entradas tiverem todas o valor 0. Agora gostava era de saber em que como este facto se aplica ás memórias flash
