a) Clear the entire usable memory to zeros. In Linux, the user region of SDRAM is
b) Set bit[0] of the first word of the memory via a write operation
c) Read the entire usable memory to confirm only the previous set bit is ONE
d) Set LED via the GPIO to indicate failure if any bit was read incorrectly
e) Shift to bit[1] and repeat (b) through (d)
f) Continuing shifting up to bit[31] and for each shift repeat (b) through (d)
g) Continue to next word in the memory, and repeat (b) to (f), till end of the usable
h) Compile and execute on both standalone (limited for 10k byte) and Linux environment
i) Divided the process into 5 corners, see Figure 29
j) FF stands for PMOS fast process type, where VT=-0.3930v; NMOS fast process type,
k) FS stands for PMOS fast process type, where VT=-0.3930v; NMOS slow process type,
l) SF stands for PMOS slow process type, where VT=-0.4284v; NMOS fast process type,
m) NN stands for PMOS nominal process type, where VT=-0.4172v; NMOS nominal
n) SS stands for PMOS slow process type, where VT=-0.4284v; NMOS slow process
o) Select 3 samples from each FF, FS, SF and NN, and 6 samples from SS
p) Put those selected samples on the MC9328MX1 Demo Board v0.1 and perform the Bit-
