摘要:
A solid state non-volatile memory unit. The memory unit includes a multi-level solid state non-volatile memory array adapted to store data characterized by a first number of digital levels. The memory unit also includes an analog-to-digital converter having an input and an output. The input of the analog-to-digital converter is adapted to receive data from the multi-level solid state non-volatile memory array. The output of the analog-to-digital converter is adapted to output a digital signal characterized by a second number of digital levels greater than the first number of digital levels.

The present invention provides an information processing unit capable of controlling reading and writing operations even when the capacity of a portable storage device is changed, a portable storage device controlled by the information processing unit, and an entertainment apparatus. The entertainment apparatus has a memory card 100, and an information processing unit 200 to which the memory card 100 is detachably connected. The memory card 100 is provided with a flash ROM 140 in which the size of a page of data capable of being read and written at a time are determined in advance, identification information 142 and an ROM size table 121. The information processing unit 200 is adapted to obtain page size-indicating information from the memory card, and control in accordance with the page size the reading and writing of data with respect to the flash ROM 140.
摘要:
Memory devices (301, 301') adapted to receive and transmit analog data signals (320, 35) representative of two or more bits, such as to facilitate increases in data transfer rates relative to devices communicating data signals indicative of individual bits. A controller (310) and a read/write channel (305) convert the digital bit patterns to analog data signals to be stored in a memory array at a particular bit capacity level in order to achieve a desired level of reliability.

The invention discloses a music-playing control method and a music playing terminal. The method comprises the following steps: optical-proximity inductive sensors in the earphone sense there is an object within their effective induction ranges, and trigger the earphone to send control signals to a music playing terminal, wherein the control signals are used for indicating the optical-proximity inductive sensors that have sensed the objects; the music playing terminal determines the motion trail of the object within a preset time period according to the received control signals and the time of receiving the control signals and executes control instructions corresponding to the motion trail. Through the invention, the music-playing control becomes simple and convenient, and the user experience is improved.
摘要:
An improved portable media device and methods for operating a media device are disclosed. According to one aspect, the portable media device can also function as a solid-state drive for data storage. The form factor of the portable media device can be hand-held or smaller, such that it is highly portable. The portable media device can use one or more status indicators. The portable media device can also include a peripheral bus connector, a rechargeable battery, and one or more input devices. According to another aspect, the portable media device has the capability to store media device status information in persistent memory before powering down. Thereafter, when the portable media device is again powered up, the stored media player status information can be retrieved and utilized. According to still another aspect, the portable media device can form and/or traverse a media asset playlist in an efficient manner.
摘要:
A portable musical instrument direct recording and playback device (10) for recording, editing, and replaying musical sounds generated by a musical instrument. The musical sounds are converted from analog to digital format, compressed for minimum storage usage, and stored in a digital storage medium. The stored signals are filed according to an indexing scheme that allows selection and retrieval of selected portions of the musical sounds. The selected portions are retrieved from storage, decompressed, converted back to analog signals, and output to a sound generating device. The operation of the device (10) is controlled by application software (19) and operating system software (21).
