Data is programmed into and read from a set of target memory cells. When reading the data, temperature compensation is provided. The temperature compensation is based on temperature information and the state of one or more neighbor memory cells. In one embodiment, when data is read from set of target memory cells, the system senses the current temperature and determines the differences in temperature between the current temperature and the temperature at the time the data was programmed. If the difference in temperature is greater than a threshold, then the process of reading the data includes providing temperature compensation based on temperature information and neighbor state information. In one alternative, the decision to provide the temperature compensation can be triggered by conditions other than a temperature differential.

A liquid immersion member is disposed around an optical member having an emergent surface from at least part of which exposure light is emitted and which holds a liquid between itself and an object opposing the emergent surface so that an optical path of exposure light between the emergent surface and the object is filled with a liquid to form an immersion space. The liquid immersion member comprises: an opening that recovers a liquid on the object with a gas; a space into which the liquid and the gas from the opening are entered; a recovery passageway into which only a liquid in the space is entered; an inner side surface that opposes at least part of a side surface of the optical member with a gap therebetween; and a recovery port that recovers at least part of a liquid in the gap.

A liquid immersion member is disposed inside an immersion exposure apparatus and at least partly around an optical member and around an optical path of exposure light that passes through a liquid between the optical member and an object. The liquid immersion member comprises: a first member, which has a first surface, a second surface that faces a direction other than that faced by the first surface, and a plurality of holes that connects the first surface and the second surface, that recovers at least some of the liquid from the space above the object opposing the first surface via the holes; a recovery passageway, wherethrough the liquid recovered via the holes of the first member flows; and a discharge part, which separately discharges a liquid and a gas from the recovery passageway. The first member comprises a first portion and a second portion. The second portion hinders a gas flowing from a space between the object and the first surface into the recovery passageway via the holes more than the first portion does.

An upper arm is connected between a positive DC terminal and the corresponding AC terminal and has an upper arm switch Q7 (Q2, Q3) and an upper arm diode. A lower arm is connected between a negative DC terminal 5 and the corresponding AC terminal and has a lower arm switch Q8 (Q5, Q6) and a lower arm diode. The apparatus also includes a smoothing reactor and a DC power source that are connected in series between the positive DC terminal and the negative DC terminal, and includes drivers to control ON/OFF of the upper and lower aim switches to output AC power. The switches Q7 and Q8 are each a normally-ON switch.
