SIMULTANEOUS READ/WRITE OPERATION
enables the device to simultaneously write data to or erase data from a bank while reading data from another bank.
Banks can be switched between using the bank addresses (A20~A15). For a description of bank blocks and addresses,
please refer to the Block Address Table and Block Size Table.

cannot read data from addresses in the same bank which have not been selected for operation. Data from these
addresses can be read using the Program Suspend or Erase Suspend function, however.
OPERATION MODES
protection and data polling. When incorporating the device into a deign, please refer to the timing charts and
flowcharts in combination with the description below.
The TC58FVT321/B321 features a Simultaneous Read/Write operation. The Simultaneous Read/Write operation
The TC58FVT321/B321 has a total of nine banks: 1 bank of 0.5 Mbits, 1 bank of 3.5 Mbits and 7 banks of 4 Mbits.
The Simultaneous Read/Write operation cannot perform multiple operations within a single bank. The table below
Note that during Auto-Program execution or Auto Block Erase operation, the Simultaneous Read/Write operation
In addition to the Read, Write and Erase Modes, the TC58FVT321/B321 features many functions including block

operation. A software reset releases ID Read Mode and the lock state which the device enters if automatic
operation ends abnormally, and sets the device to Read Mode. A hardware reset terminates operation of the
device and resets it to Read Mode. When reading data without changing the address immediately after power-on,
either input a hardware Reset or change CE from H to L.
To read data from the memory cell array, set the device to Read Mode. In Read Mode the device can perform
The device is automatically set to Read Mode immediately after power-on or on completion of automatic
