    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...

    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.)
