11. DATA PROTECTION
The TC58FVM6(T/B)5B includes a function which guards against malfunction or data corruption.

than 3 ns (Typ.) input on WE , CE or OE . However, if a glitch exceeding 3 ns (Typ.) occurs and the glitch is input to the
device malfunction write may occur.
The device uses standard JEDEC commands. It is conceivable that, in extreme cases, system noise may be misinterpreted as
part of a command sequence input and that the device will acknowledge it. Then, even if a proper command is input, the device
may not operate. To avoid this possibility, clear the Command Register before command input. In an environment prone to
system noise, Toshiba recommends input of a software or hardware reset before command input.
11.3. Protection against Malfunction at Power-on
does not latch the command on the first rising edge of WE or CE . Instead, the device automatically Resets the Command
Register and enters Read Mode.
