The RESET signal (RESET#) is an asynchronous signal that triggers any time it drops
LOW, and there are no restrictions about when it can go LOW. After RESET# goes LOW, it
must remain LOW for 100ns. During this time, the outputs are disabled, ODT (R
off (High-Z), and the DRAM resets itself. CKE should be brought LOW prior to RESET#
being driven HIGH. After RESET# goes HIGH, the DRAM must be reinitialized as though
a normal power up were executed (see Figure 106 on page 160). All refresh counters on
the DRAM are reset, and data stored in the DRAM is assumed unknown after RESET# has
gone LOW.
