    摘要: Systems and methods for choosing a memory block for the storage of data based on a frequency with which data is updated are disclosed. In one implementation, a memory management module of a non-volatile memory system receives a request to open a free memory block for the storage of data. The memory management module determines a frequency with which the data is updated. The memory management module then opens a memory block of a first portion a free block list that is associated with low program/erase cycle counts in response to determining that the data will be frequently updated or opens a memory block of a second different portion of the free block list that is associated with high program/erase cycle counts in response to determining that the data is not frequently updated. The memory management module then stores the data in the open memory block of the non-volatile memory.

    摘要: Systems and methods for controlling blocks in a memory device using a health indicator (such as the failed bit count) for the blocks are disclosed. However, the health indicator may exhibit noise, thereby resulting in an unreliable indicator of the health of the blocks in the memory device. In order to filter out the noise, a rolling average of the health indicator may be determined, and compared to the current health indicator. The comparison with the rolling average may indicate whether the current health indicator is an outlier, and thus should not be used. The health indicator may also be used to predict a future health indicator for different blocks in the memory device. Using the predicted future health indicator, the use of the blocks may be changed in order to more evenly wear the blocks.

    摘要: A memory system or flash card may include a mechanism for memory cell measurement and analysis that independently measures/predicts memory wear/endurance, data retention (DR), read disturb, and/or remaining margin. These effects may be independently quantified by analyzing the state distributions of the individual voltage levels of the cells. In particular, a histogram of cell voltage distributions of the memory cells can be analyzed to identify signatures for certain effects (e.g. wear, DR, read disturb, margin, etc.). Those measurements may be used for block cycling, data loss prediction, or adjustments to memory parameters. Pre-emptive action at the appropriate time based on the measurements may lead to improved memory management and data management. That action may include calculating the remaining useful life of data stored in memory, cycling blocks, predicting data loss, trade-off or dynamic adjustments of memory parameters.

    摘要: To maintain stability of memory array operations, a supplemental current can supply a common source line of a memory array so that the combined current from the memory array and supplemental current is at least a minimum regulation current level. When enabled for sensing operations, a driver circuit maintains the common source line's voltage level. A current subtractor circuit determines the difference between a reference current and a current proportional to the current flowing from the array, where the reference current is proportional to the minimum regulation current. The difference current is then mirrored by a self-adjusting current loop and supplied to the common source line to maintain its current level.
