Abstract
A pulse-based memory read-out device, including: a pulse generator at a first end of a bit line and a detector at a second end of the bit line. The pulse generator is configured to send an electrical pulse along the bit line from the first end of the bit line. The detector is configured to: detect the electrical pulse at the second end; and output a digital signal representing a current state of a selected memory cell in the bit line, wherein the digital signal is based on an amplitude of the electrical pulse at the second end.
Claims20
A pulse-based memory read-out device, comprising:
- a pulse generator at a first end of a bit line, wherein the pulse generator is configured to send an electrical pulse along the bit line from the first end of the bit line;
- and
- a detector at a second end of the bit line, wherein the detector is configured to:
- detect the electrical pulse at the second end;
- and
- output a digital signal representing a current state of a selected memory cell in the bit line, wherein the digital signal is based on an amplitude of the electrical pulse at the second end.
A flash storage device, comprising:
- an array of memory cells, wherein the memory cells are arranged in columns of bit lines and rows of word lines;
- a pulse generator at a first end of each bit line, wherein each of the pulse generators is configured to send an electrical pulse along one of the bit lines from the first end of the bit line corresponding to the selected memory cell;
- and
- a detector at a second end of each bit line, wherein each detector is configured to:
- detect the electrical pulse at the second end of the corresponding bit line;
- and
- output a digital signal representing a current state of the selected memory cell, wherein the digital signal is based on a voltage level of the electrical pulse at the second end of the corresponding bit line.
A method for reading out a flash memory device, the method comprising:
- generating an electrical pulse at a first end of a bit line, wherein the bit line comprises a selected memory cell between the first end and a second end of the bit line;
- detecting the electrical pulse at the second end via a detector;
- and
- outputting a digital signal representing a current state of the selected memory cell, wherein the digital signal is based on an amplitude of the electrical pulse at the second end.
