Abstract
A storage device includes a storage array having a group of storage elements. Each storage element can written to a discrete set of physical states. A read circuit selects one or more storage elements and generates, for each selected storage element, an analog signal representative of the physical state of the selected storage element. A signal processing circuit processes the analog signal to generate a plurality of outputs, with each output representing a degree of an association of the selected storage element with a different subset of one or more of the discrete set of physical states.
Claims19
A storage system comprising:
- a first section having:
- a storage array including a plurality of storage elements, each storage element operable to be written to one of a discrete set of N physical states;
- a read circuit for selecting one or more storage elements and generating, for each selected storage element, an analog signal representative of the physical state of the selected storage element;
- and
- a modulation circuit for accepting the analog signal to form a modulated representation of the analog signal from the read circuit capable of representing greater than N different states;
- and
- a second section interfacing the first section having:
- a demodulation circuit for accepting the modulated representation of the analog signal from the modulation circuit to recover the analog signal;
- and
- a signal processing circuit for processing the recovered analog signal to generate a plurality of outputs, each output representing a degree of an association of the selected storage element with a different subset of one or more of the discrete set of physical states.
