RAM corruption, possible eMMC corruption

i don't know how easily to test ram memory, but i'm skilled enough to use command "dd" to test emmc mem. however, booting sdcard is necessary and tests still wipes data from emmc.
basic idea is to create 1 gigabyte of random bytes to write to disk and then read and verify it. knowledge of dd, /dev/urandom and sha256 is required.
at this point, test booting from sdcard first, and maybe proceed to test emmc.
