    the hardware secrets website explains them as the following:

    "# tRP: RAS Precharge. The time it takes between disabling the access to a line of data and the begin of the access the another line of data.
    # tRAS: Active to Precharge Delay. How long the memory has to wait until the next access to the memory can be initiated. "

    so does tRAS include tRP? or is it the other way around... maybe im reading it wrong?

    thanks for anyhelp...

    EDIT:
    nevermind. behold the beauty of reading something all the way through to find the answer...

    "Active to Precharge Delay (tRAS): After an “Active” command is issued, another “Precharge” command cannot be issued until tRAS has been elapsed. So this parameter limits when the memory can start reading (or writing) a different row."

    tee hee (whoops.)
