摘要： A permanent storage memory unit comprises a plurality of information bits stored in a predetermined manner at a plurality of address stations at either a ''''0'''' or a ''''1'''' level. The logic level at a particular address station is determined by the presence or absence of a potentially operative data-switching device. The address stations may be defined by the respective intersections of a plurality of rows and columns. The addressselecting means include column-selecting circuitry merged with the data devices at each of the columns, and row select circuitry operatively connected to the data devices.

摘要： First data is read out of a core storage array of a memory component over a first time interval constrained by data output bandwidth of the core storage array. After read out from the core storage array, the first data is output from the memory component over a second time interval that is shorter than the first time interval and that corresponds to a data transfer bandwidth greater than the data output bandwidth of the core storage array.

摘要： Methods, apparatus, systems and articles of manufacture to facilitate atomic compare and swap in cache for a coherent level 1 data cache system are disclosed. An example system includes a cache storage; a cache controller coupled to the cache storage wherein the cache controller is operable to: receive a memory operation that specifies a key, a memory address, and a first set of data; retrieve a second set of data corresponding to the memory address; compare the second set of data to the key; based on the second set of data corresponding to the key, cause the first set of data to be stored at the memory address; and based on the second set of data not corresponding to the key, complete the memory operation without causing the first set of data to be stored at the memory address.

摘要： One example includes a memory circuit. The circuit includes a memory array arranged as rows and columns of memory cells. An array portion stores a respective memory word in a given one of the rows in response to a word-write signal corresponding to a write address of the given one of the rows and in response to a plurality of bit-write signals associated with the plurality of columns, and reads a respective memory word from a given one of the rows in response to a word-read signal corresponding to a read address of the given one of the rows and in response to a plurality of bit-read signals associated with the plurality of columns. The circuit also includes a write-through detection system that activates an analog bypass portion to read the memory word from the analog bypass portion in response to the read address being equal to the write address.

The method of operating a memory system may include receiving a first program command, and performing an operation corresponding to the first program command, receiving a second program command while performing the operation corresponding to the first program command, delaying setting of a queue status register for the second program command by a first wait time, receiving a third read command before the first wait time elapses, and setting the queue status register for the third read command before setting the queue status register for the second program command.

摘要： A memory system includes: a memory device; and a controller suitable for controlling the memory device to perform a serial read operation by providing a serial read command and a start physical address for the serial read command when an external read command includes a request for the serial read operation, the serial read command includes consecutive physical address numbers information, in response to the serial read command, the memory device sets a read bias, reads data stored therein with the set read bias according to the start physical address and the consecutive physical address numbers information, and then discharges the read bias.
