摘要： A memory circuit with a word line driver and control circuitry is disclosed. The word line driver receives a first voltage reference signal, a second voltage reference signal, and an input signal. The word line driver has an output coupled to a word line. The control circuitry is configured to deselect the word line by applying the input signal to the input of the word line driver. For example, in a program operation the word line is deselected to indicate that the word line is not programmed, and another word line is selected to be programmed. During an operation in which the word line is deselected and another word line is selected, the word line discharges through both of a first p-type transistor and a first n-type transistor of the word line driver.

摘要： The storage layer such as a nitride layer of a nonvolatile memory cell has two storage parts storing separately addressable data, typically respectively proximate to the source terminal and the drain terminal. The applied drain voltage while sensing the data of one of the storage parts depends on the data stored at the other storage part. If the data stored at the other storage part is represented by a threshold voltage exceeding a minimum threshold voltage, then the applied drain voltage is raised. This technology is useful in read operations and program verify operations to widen the threshold voltage window.

摘要： A method of programming data stored in a memory, which comprises a number of user-defined blocks, a number of manufacture-defined blocks, and an information block, includes the following steps. A programming address pointing to a user-defined block in the memory and programming data is obtained. After that, it is determined whether there is an empty manufacture-defined block among a number of user-defined blocks in the memory. If so, an information block in the memory is programmed to store the programming address and a replacing address pointing to the empty manufacture-defined block. The empty manufacture-defined block is programmed to store the programming data.

摘要： Source-side sensing techniques described herein determine the data value stored in a memory cell based on the difference in current between the read current from the source terminal of the memory cell and a sink current drawn from the read current. The sink current is drawn in response to the magnitude of a reference current provided by a reference current source such as a reference cell.
