PSRAM is SDRAM , but at .00007 amps !

    The       M 69 AW 024
       2 megaByte    DRAM is so low
     power ,  they did not want to call it DRAM ,
    so they tagged it  PSRAM

    All the transistor methods are pulling about same
    milliwatts/megahertz , so CMOS is same as DRAM .

    CMOS at 50Mhz gets hot !  So why not just use DRAM !!
   Besides , 2MegaBytes is impossible ,in CMOS at
  that price and density ...

 Only thing CMOS can do better is holding data at room
 temp , 25C .
  64MByte can be held at several microamps at 2.0vdc .


 Ill be building a ARM-9 PC and i always do stuff better than
 anyone ,so my embedded ARM-9 will boot OpSys from Flash
 to PSRAM and , no need to reboot , but once a week .
  You turn it off and OpSys is held in PSRAM , so it
 takes  0.1 second to boot ...

Not so fast, cowboy.

A project that we just completed and is nearly identical to what you
described (ARM9 + PSRAM) has enabled us to boot from flash in 50
milliseconds.

We do some stuff better than you, always.
