  • Publication number: 20220027067
    Abstract: Methods and apparatuses for improve data clock to reduce power consumption are presented. The apparatus includes a memory configured to receive a data clock from a host via a link and to synchronize the data clock with the host. The memory includes a clock tree buffer configured to toggle based on the data clock to capture write data or to output read data and a command decoder configured to detect a data clock suspend command while the data clock is synchronized between the host and the memory. The clock tree buffer is configured to disable toggling based on the data clock in response to the command decoder detecting the data clock suspend command. the host includes a memory controller configured to provide a data clock suspend command to the memory via the link while the data clock is synchronized between the host and the memory.

  • Publication number: 20210343331
    Abstract: In a conventional memory subsystem, a memory controller issues explicit refresh commands to a DRAM memory device to maintain integrity of the data stored in the memory device when the memory device is in an auto-refresh mode. A significant amount of power may be consumed to carry out the refresh. To address this and other issues, it is proposed to allow a partial refresh in the auto-refresh mode in which the refreshing operation may be skipped for a subset of the memory cells. Through such selective refresh skipping, the power consumed for auto-refreshes may be reduced. Operating system kernels and memory drivers may be configured to determine areas of memory for which the refreshing operation can be skipped.

  • Patent number: 10922168
    Abstract: Errors can be introduced when data is transferred over a link between two entities such as between a host and a memory. Link error protection schemes can be implemented to detect and correct errors that occur on the link to enhance transmission reliability. However, these benefits are not without costs since such protection schemes increase both latency and power consumption. In one or more aspects, it is proposed to dynamically adjust the level of link error protection applied to match any change in the operating environment. For example, likelihood of link errors strongly correlates with the link speed. If the link speed is increased, a greater level of link error protection can be applied to counteract the increase in the link errors. If the link speed is decreased, the level of protection can be decreased so that latency and power consumption penalties can be minimized.

  • Publication number: 20200401474
    Abstract: Disclosed are techniques for generating a parity check matrix representing an error correcting code (ECC) for protecting a plurality of bits of a message. In an aspect, a method includes initializing a matrix M to store selected three-bit codes, selecting a first three-bit code from a set L of three-bit combinations of a number of bits n of the ECC that minimizes a sum of squared row weights of each row of the matrix M, comparing the first three-bit code with each of a plurality of error syndromes, and calculating, based on no comparison of the first three-bit code with each of the plurality of error syndromes, new error syndromes and storing the new error syndromes, wherein the new error syndromes are calculated by comparing the first three-bit code with each three-bit code in the matrix M, and storing the first three-bit code in the matrix M.

  • Patent number: 10852809
    Abstract: Power saving techniques for memory systems are disclosed. In particular, exemplary aspects of the present disclosure contemplate taking advantage of patterns that may exist within memory elements and eliminating duplicative data transfers. Specifically, if data is repetitive, instead of sending the same data repeatedly, the data may be sent only a single time with instructions that cause the data to be replicated at a receiving end to restore the data to its original repeated state.

  • Patent number: 10394724
    Abstract: Systems and method are directed to reducing power consumption of data transfer between a processor and a memory. A data to be transferred on a data bus between the processor and the memory is checked for a first data pattern, and if the first data pattern is present, transfer of the first data pattern is suppressed on the data bus. Instead, a first address corresponding to the first data pattern is transferred on a second bus between the processor and the memory. The first address is smaller than the first data pattern. The processor comprises a processor-side first-in-first-out (FIFO) and the memory comprises a memory-side FIFO, wherein the first data pattern is present at the first address in the processor-side FIFO and at the first address in the memory-side FIFO.
