Abstract
A semiconductor device is provided that can perform simultaneous writing of a large number of bits, without an increase in chip size. This semiconductor device includes: a write data bus via which data are written into memory cells; a read data bus via which the data are read from the memory cells; a first write amplifier that writes data into the memory cells via the read data bus at the time of high-speed writing; a second write amplifier that writes data into the memory cells via the write data bus at the time of high-speed writing; a first sense amplifier that reads verified data from the memory cells via the read data bus; and a second sense amplifier that reads verified data from the memory cells via the write data bus.
Claims28
A semiconductor device comprising:
- a write data bus via which data are written into memory cells;
- a read data bus via which data are read from the memory cells;
- and
- a first write amplifier that writes data into the memory cells via the read data bus at the time of given writing.
A semiconductor device comprising:
- shield lines that shield a read data bus via which data are read from memory cells;
- and
- a third write amplifier that writes data into the memory cells via the shield lines.
A method of writing data comprising the steps of:
- writing data into memory cells via a write data bus;
- reading data from the memory cells via a read data bus;
- and
- writing data into the memory cells via the read data bus at the time of given writing.
A method of writing data comprising the steps of:
- reading data from memory cells via a read data bus;
- and
- writing, at the time of given writing, data into the memory cells via shield lines that shield the read data bus.
