A method for sensing voltage on an internal node in an integrated circuit includes applying a voltage larger than a threshold value to a first pad, generating from the activation voltage a potential for a sensing circuit and coupled to the internal node, and coupling an output of the sensing circuit to a second pad on the integrated circuit when the activation voltage is present on the first pad. A sensing circuit includes first and second pads, a voltage-sensor circuit having an input coupled to an internal node and a power connection coupled to a sensor power node. A circuit is configured to place a supply potential on the sensor power node when a threshold value is on the first pad. A switch coupled between the sensing circuit and the second pad turns on when the supply potential is on the voltage sensor power node.

An array (200; 202) of memory cells having a predetermined group (301) of storage cells (203; 205; 306) , arranged in a row, also have an arrangement of one or more reference cells (201; 207; 304, 307) fabricated to be adjacent to or proximate to the row of storage cells. The reference cells are written to, erased, or programmed when the storage cells are written to, erased, or programmed. The same number of write, erase, or program cycles and the proximity of the reference cells to the storage cells maintain an operational matching of the storage cells and reference cells.

A charge pump generates a voltage higher than an intermediate voltage and a regulator circuit provides a first regulated voltage higher than the intermediate voltage. A second stage includes a regulator stage using the first voltage to provide the intermediate voltage from the first voltage. A charge pump provides a pump output voltage. The pump output voltage is divided and the divided voltage is presented to a first comparator that compares it with a reference voltage. The first comparator drives the gate of a first MOS transistor to regulate the pump output voltage to a regulated voltage related to the reference voltage. The regulated voltage is presented to a second comparator that compares it with the reference voltage. The second comparator drives the gate of a second MOS transistor to downconvert the regulated output voltage to an intermediate voltage related to the reference voltage.
摘要:
A flash memory programming process incorporates two charge pumps per byte of bit cells. Placing a data "one” value in each bit cell erases an entire memory device. Before programming each cell, a prospective data content is scrutinized. If a data "zero" is to be applied to the bit cell, a charge pump engages to bias the cell and activate a hot electron injection process to affect the programming. If a data "one" is to be applied to the bit cell, no programming activity is undertaken and the process increments to the next bit cell in the data structure. Therefore, total programming time is reduced proportionally to the number of data "one" bits to be programmed. Where more than one charge pump is engaged in parallel to a data structure, total programming time is further reduced when two data "one" values are to be programmed in parallel.

A medical device is provided that performs a requested action. The requested action may be communicated, for example, to the medical device via email messages. After performing the requested action, a response that is dependent upon the requested action is generated. The generated response is then sent on a network from the medical device as an email message.

A high-voltage charge pump circuit includes a charge pump circuit. First high-voltage output circuit is configured to set an output voltage of the charge pump at a first voltage level selected for regular programming and erasing memory cells. A second high-voltage output circuit is configured to set the output voltage of the charge pump at a second voltage level selected for walkout of device junctions, the second voltage level being higher than the first voltage level. A third high-voltage output circuit is configured to set the output voltage of the charge pump at a third voltage level selected for guardband programming and erasing, the third voltage level being lower than the second voltage level and higher than the first voltage level. Selection circuitry selectively couples one of the first, second, and third high- voltage output circuits to the output of the high-voltage charge pump circuit.
摘要:
An improved CMOS high-voltage latch (100) stores data bits to be written to memory cells of a non- volatile memory has two cross- coupled CMOS inverters (102, 104). One inverters (104) has a pull-down leg that includes a pass-gate high-voltage NMOS transistor (116) connected between a latch output node and a second high-voltage, low-threshold NMOS pull- down transistor (118), connected to ground. A gate of the NMOS transistor (116) receives a standby signal with a logic HIGH value to turn on the NMOS transistor (116) when the CMOS latch (100) is in a data-loading mode of operation and during a high-voltage write mode of operation. The NMOS transistor (118) thereby limits the voltage across the second NMOS pull-down transistor (118) to less than the standby signal, reducing punch-through current and drain-to-substrate leakage from second NMOS pull-down transistor (118).
