Abstract
A semiconductor storage device and control method are provided. The semiconductor storage device includes a storage unit including a plurality of storage elements specified by addresses and divided into a plurality of blocks each corresponding to a plurality of the addresses, a write address decoding circuit that decodes a write address specifying a block to write data, a write buffer provided in a write signal path to input write data including write address to the block specified by the write address and a write buffer control unit that disables a write buffer provided in the write signal path for inputting the write data to blocks other than a block including a write address decoded by the write address decoding circuit.
Claims12
A semiconductor storage device comprising:
- a storage unit including a plurality of storage elements specified by addresses and divided into a plurality of blocks each corresponding to a plurality of the addresses;
- a write address decoding circuit that decodes a write address specifying a block to write data;
- a write buffer provided in a write signal path to input write data including write address to the block specified by the write address;
- and
- a write buffer control unit that disables a write buffer provided in the write signal path for inputting the write data to blocks other than a block including a write address decoded by the write address decoding circuit.
A semiconductor storage device comprising:
- a storage unit including a plurality of storage elements specified by addresses and divided into a plurality of blocks each corresponding to a plurality of the addresses;
- a read address decoding circuit that decodes a read address specifying a block to read data from;
- a read buffer provided in a read signal path to output read data from the blocks specified by the read address;
- and
- a read buffer control unit that disables a read buffer provided in the read signal path for outputting the read data from blocks other than a block including a read address decoded by the read address decoding circuit.
A method for controlling a semiconductor storage device including a storage unit including a plurality of storage elements specified by addresses and divided into a plurality of blocks each corresponding to a plurality of the addresses, and a write buffer provided in a write signal path to input write data including write address to the block specified by the write address, the method comprising:
- decoding a write address specifying a block to write data;
- and
- disabling a write buffer provided in the write signal path for inputting the write data to blocks other than a block including a write address decoded by the write address decoding.
A method for controlling a semiconductor storage device including a storage unit including a plurality of storage elements specified by addresses and divided into a plurality of blocks each corresponding to a plurality of the addresses, and a read buffer provided in a read signal path to output read data from the block specified by the read address, the method comprising:
- decoding a read address specifying a block to write data;
- and
- disabling a read buffer provided in the read signal path for outputting the read data from blocks other than a block including a read address decoded by the read address decoding.
A device comprising:
- a storage unit divided into a plurality of blocks;
- a decoding circuit that decodes an address specifying a block of the plurality of blocks;
- a buffer provided in a signal path to input data to the specified block;
- and
- a control unit that disables a buffer for inputting data to blocks of the plurality of blocks other than the specified block.
A method for controlling a device, comprising:
- decoding an address specifying a block of a plurality of blocks;
- and
- disabling a buffer for inputting data to blocks of the plurality of blocks other than the specified block.
