Abstract
The flash memory system according to the embodiment of the present invention is characterized by programming a selected page in a quantization signal generating operation, providing a reference read voltage to a selected word line connected to the selected page, A flash memory for generating a flash memory; And a memory controller for receiving a quantized signal from the flash memory and generating a response using the quantized signal, wherein the memory controller receives an challenge from a host and the flash memory performs the quantized signal generation.
Claims20
A flash memory system comprising:
- a flash memory for programming a selected page and providing a reference read voltage to a selected word line coupled to the selected page during a quantization signal generating operation and generating a quantized signal by reading the selected page;
- and
- a memory controller for receiving the quantized signal from the flash memory and generating a response using the quantized signal,
- wherein the memory controller receives a challenge from a host and controls the flash memory to perform the quantization signal generating operation.
A flash memory system comprising:
- a flash memory for programming a memory block such that a threshold voltage distribution is grouped in units of subblocks and generating a quantized signal by providing a reference read voltage to selected pages of selected subblocks during a quantization signal generating operation;
- And a memory controller for receiving the quantized signal from the flash memory and generating a response using the quantized signal
- Wherein the memory controller receives an challenge from a host and controls the flash memory to perform the quantization signal generating operation.
A method of generating a quantized signal of a flash memory system,
- receiving a challenge from a host;
- selecting a word line according to address information included in the challenge, and programming a selected page connected to the selected word line;
- and
- providing a reference read voltage to the selected word line, and generating a quantized signal by reading the selected page,
- wherein the flash memory system generates a response using the quantized signal and provides the response to the host.
