Nonvolatile semiconductor storage device with interface functions |
摘要 |
A nonvolatile semiconductor storage device directly connected to CPU buses and general-purpose buses is provided. The device has a nonvolatile memory cell array with block units including a plurality of sectors. Each sector stores user data by being specified each address. The device has a sequencer which judges whether predetermined types of the access operation is carried out or not. The judgment is achieved based on: a command register which sets a command to specify type of access operation to the array; an address register which sets the access address; a count register which sets a number of the sectors to be accessed; a status register which holds status indicating whether processing according to the command set to the command register; status; and the command. The sequencer accesses to the array based on the address set and the number of sectors when the access operation is carried out.
