Patent number: 9683904Abstract: A temperature sensor circuit has a reference voltage generator that is trimmable at two temperatures for increased accuracy. The reference voltage generation section generates a reference voltage, the level of which is trimmable. A voltage divider section is connected to receive the reference voltage from the reference voltage generation section and generate a plurality of comparison voltage levels determined by the reference voltage and a trimmable resistance. An analog-to-digital converter can then be connected to a temperature dependent voltage section to receive the temperature dependent output voltage, such as a proportional to absolute temperature type (PTAT) behavior, and connected to the voltage divider section to receive the comparison voltage levels. The analog to digital converter generates an output indicative of the temperature based upon a comparison of the temperature dependent output voltage to the comparison voltage levels.Type: GrantFiled: November 30, 2016Date of Patent: June 20, 2017Assignee: SANDISK TECHNOLOGIES LLCInventors: Masahide Matsumoto, Ryuji Yamashita

Patent number: 8842471Abstract: In non-volatile memory devices, a write typically consists of an alternating set of pulse and verify operations. At the end of a pulse, the device must be biased properly for an accurate verify, after which the device is re-biased for the next pulse. The intervals between the pulse and verify phases are considered. For the interval after a pulse, but before establishing the verify conditions, the source, bit line, and, optionally, the well levels can be equalized and then regulated at a desired DC level. After a verify phase, but before applying the biasing the memory for the next pulse, the source and bit line levels can be equalized to a DC level.Type: GrantFiled: August 9, 2012Date of Patent: September 23, 2014Assignee: SanDisk Technologies Inc.Inventors: Hao Thai Nguyen, Juan Carlos Lee, Seungpil Lee, Masahide Matsumoto, Jongmin Park, Man Lung Mui, Sung-En Wang

Patent number: 6140615Abstract: A heater apparatus includes a flat-shaped heater portion attachable to a vessel such as a water tank, and a controller for controlling the heater portion. The heater portion includes a flat heater, a first temperature sensor for detecting temperature of the flat heater, and a second temperature sensor for detecting temperature of what is contained in the vessel or water tank. The controller keeps the temperature constant inside the vessel in accordance with the temperature detected by the second temperature sensor. If the rate of rise in temperature detected by the first temperature sensor is faster than is deemed normal, the controller stops current flowing to the flat heater.Type: GrantFiled: January 14, 1999Date of Patent: October 31, 2000Assignee: Sanki Consys Co., Ltd.Inventor: Masahide Matsumoto

Patent number: 5995431Abstract: A circuit is designed with a memory array (102) having a plurality of memory cells arranged in rows and columns (204, 206, 210, 212). The memory array has a plurality of bit line pairs (202, 208, 282, 284) with each bit line pair connected to a respective column of memory cells and a bit line reference terminal (254). A control circuit (700) produces a control signal, the control signal having a first voltage for a first time, a second voltage for a second time and a third voltage for a third time. A precharge circuit (350, 352) connects at least one bit line pair to the bit line reference terminal, responsive to the first voltage for the first time and the second voltage for the second time. The precharge circuit disconnects the at least one bit line pair from the bit line reference terminal, responsive to the third voltage for the third time.Type: GrantFiled: June 10, 1998Date of Patent: November 30, 1999Assignee: Texas Instruments IncorporatedInventors: Takashi Inui, Masahide Matsumoto, Kiyotaka Okuzawa
