    Abstract: This disclosure provides sense amplifier technology for a memory device that uses multiple sense methods. In one implementation, a memory device is configured with both digital sense circuitry and analog sense circuitry, which can be alternatively or simultaneously used. In another implementation, use of the specific sense circuitry is dependent upon a mode or command. In another embodiment, the specific sense circuitry utilizes is responsive to predetermined tasks. In one contemplated application, a multilevel nonvolatile memory device (e.g., a flash memory device) uses (a) digital sense circuitry during program-verify operations, where it is desired to minimize power and maximize bitline impact and where latency is already to a certain extent fixed by programming operation and (b) analog sense circuitry in responding to read commands, to provide relatively high performance (at the expense of greater power consumption). Different sets of circuits can be used or circuitry can be shared and/or configured for multisense operation, depending on the specific design.

    Abstract: A sensing amplifier (100) for a memory cell comprises a selection stage (102) that outputs one of a reference current (Iref) and a memory cell current (Icell) during a first period and the other of the reference current (Iref) and the memory cell current (Icell) during a second period. The first period and the second period are non-overlapping. An input stage (104) generates a first current based on the one of the reference current (Iref) and the memory cell current (Icell) during the first period and generates a second current based on the other of the reference current (iref) and the memory cell current (Icell) during the second period. A sensing stage (106) senses a first value based on the first current and stores the first value during the first period, senses a second value based on the second current during the second period and compares the first value to the second value.

    Abstract: The present invention facilitates more accurate data reads by compensating for parasitic behavior (662) - thus regulating the voltage at the drain (610) of a core memory cell (604) rather than at the output of a sensing circuit. More particularly, respective voltages at one or more nodes (660), such as the start of a bitline at a sensing circuit, for example, are adjusted to compensate for voltage drops that may occur due to parasitic behavior (662). Maintaining the substantially constant voltage levels at core memory cells allows comparisons to be made under ideal conditions while reducing the side leakages in virtual ground schemes. This mitigates margin loss and facilitates more reliable data sensing.

    Abstract translation: 本发明通过补偿寄生行为(662)来促进更准确的数据读取,从而调节核心存储器单元(604)的漏极(610)处的电压,而不是在感测电路的输出处。 更具体地,例如调整一个或多个节点(660)处的各个电压(例如感测电路处的位线开始)以补偿由于寄生行为可能发生的电压降(662)。 在核心存储器单元处保持基本恒定的电压电平允许在理想条件下进行比较,同时减少虚拟接地方案中的侧漏。 这减轻了边际损失,并促进了更可靠的数据传感。

    Abstract: A sense amplifier system for sensing the charge of a charge-­storing means (601) comprises a first and second charge reference means (600a, 600b) connected in parallel and similar to the charge-storing means (601) and having respectively opposite polarization. The charge reference means (600a, 600b) and the charge-storing means (601) have a common input node (WL), and first and second pseudo-differential reference sense amplifiers (RSA1, RSA2) are connected with output nodes (RBL1, RBL2) of the charge reference means (600a, 600b) for generating reference signals to a common reference node (CHREF) connected with a pseudo-differential sense amplifier (SA). The pseudo-differential sense amplifier (SA) has a second input for receiving an output signal from the charge-storing means (601) and generates an output signal indicative of a polarization state of the charge-storing means. Another embodiment adapted for sensing the charges of a plurality of charge-storing means (701) and comprising at least two pairs of charge reference means is also described. A non-volatile matrix-addressable memory system comprising an electrical polarizable dielectric memory material exhibiting hysterisis and a sense amplifier system as described is also claimed.
