摘要:
A system for programming non-volatile storage is proposed that reduces the impact of interference from the boosting of neighbors. Memory cells are divided into two or more groups. In one example, the memory cells are divided into odd and even memory cells; however, other groupings can also be used. Prior to a first trigger, a first group of memory cells are programmed together with a second group of memory cells. Subsequent to the first trigger and prior to a second trigger, the first group of memory cells are programmed separately from the second group of memory cells. Subsequent to the second trigger, the first group of memory cells are programmed together with the second group of memory cells. Before and after both triggers, the first group of memory cells are verified together with the second group of memory cells.
摘要:
Methods and circuitry are present for improving performance in non-volatile memory devices by allowing the inter-phase pipelining of operations with the same memory, allowing, for example, a read operation to be interleaved between the pulse and verify phases of a write operation. In the exemplary embodiment, the two operations share data latches. In specific examples, at the data latches needed for verification in a multi-level write operation free up, they can be used to store data read from another location during a read performed between steps in the multi-level write. In the exemplary embodiment, the multi-level write need only pause, execute the read, and resume the write at the point where it paused.

In a memory in integrated circuit form, organized as a matrix of rows and columns, a current detection circuit is connected at input to at least one column of the memory and at output to a corresponding read circuit. The current detection circuit includes a transistor connected between the input and the output and controlled at its gate by a reference current detection circuit.

A hot count records the number of erase operations experienced by a block. The hot count is stored in an overhead data area of the block and is updated by circuits located on the same substrate as the block. Where a memory has two or more planes, each plane has circuits for updating hot counts.

In a differential amplifier with asymmetrical outputs, the gates of the two load transistors are at the same specified potential and the voltage at the connection node between the load transistor and the amplifier transistor of one arm is stabilized by means of a compensation structure. This amplifier works at low VCC (e.g., less than 2 volts) while at the same time having high gain.
