Abstract: A cache includes an upstream port, a cache memory for storing cache lines each having a line width, and a cache controller. The cache controller is coupled to the upstream port and the cache memory. The upstream port transfers data words having a transfer width less than the line width. In response to a cache line fill, the cache controller selectively determines data bus inversion information for a sequence of data words having the transfer width, and stores the data bus inversion information along with selected inverted data words for the cache line fill in the cache memory.

Abstract: A method for operating a memory device includes initiating an access operation to a corresponding row of an array of bit cells of the memory device. Responsive to an expansion mode signal having a first state, the method further includes dynamically operating each column of a plurality of columns of the array to access each bit cell of a corresponding row within the plurality of columns during the access operation. Alternatively, responsive to the expansion mode state signal having a second state different than the first state, the method includes dynamically operating each column of a first subset of columns of the plurality of columns to access each bit cell of a corresponding row within the first subset of columns during the access operation, and maintaining each column of a second subset of columns of the plurality of columns in a static state during the access operation.

Abstract: A data processing system includes a processing unit that forms a base die and has a group of through-silicon vias (TSVs), and is connected to a memory system. The memory system includes a die stack that includes a first die and a second die. The first die has a first surface that includes a group of micro-bump landing pads and a group of TSV landing pads. The group of micro-bump landing pads are connected to the group of TSVs of the processing unit using a corresponding group of micro-bumps. The first die has a group of memory die TSVs. The subsequent die has a first surface that includes a group of micro-bump landing pads and a group of TSV landing pads connected to the group of TSVs of the first die. The first die communicates with the processing unit using first cycle timing, and with the subsequent die using second cycle timing.

Abstract: A test circuit for a static random access memory (SRAM) array includes a plurality of stages coupled in a ring. Each stage includes a plurality of bit cells to store information, a bit line and a complementary bit line coupled to the plurality of bit cells, and a plurality of word lines coupled to the plurality of bit cells. Subsets of the plurality of word lines of each of the plurality of stages are selectively enabled based on signals asserted on the complementary bit line of another one of the plurality of stages. The test circuit also includes inversion logic deployed between two of the plurality of stages.

Abstract: An integrated circuit (IC) generates clock delay control signals based on its operational voltage level. The clock delay control signals are routed to corresponding clock gating logic that controls the synchronous capturing of the outputs of corresponding signal paths. The clock gating logic delays the clock signal used by the corresponding flip-flop in response to an assertion of the corresponding received clock delay control. Thus, the clock signal used to capture the outputs of certain signal paths may be delayed under certain voltage conditions. This selective clock path delay for different signal paths enables the IC to use a higher clock frequency, or more reliably latch the path outputs at a certain clock frequency, even though different signal paths may exhibit different relative path delays under different operating voltage conditions.
Abstract translation: 集成电路(IC)根据其工作电压电平产生时钟延迟控制信号。 时钟延迟控制信号被路由到对应的时钟门控逻辑,其控制相应信号路径的输出的同步捕获。 响应于对应的接收时钟延迟控制的断言,时钟门控逻辑延迟由相应触发器使用的时钟信号。 因此,用于捕获某些信号路径的输出的时钟信号可能在某些电压条件下被延迟。 即使在不同的工作电压条件下不同的信号路径可能表现出不同的相对路径延迟,不同信号路径的这种选择性时钟路径延迟使得IC能够使用更高的时钟频率,或者更可靠地锁定一定时钟频率的路径输出。
