  • Patent number: 11923029
    Abstract: According to one embodiment, a memory system includes: a controller configured to execute an error correction process on first data read from a first area at a first address of a memory device and determine a read level used for reading data at the first address according to a result of the correction process. The controller executes the correction process on first frame data of the first data. When the correction process on the first frame data has failed, the controller executes the correction process on second frame data of the first data. When the correction process on the second frame data has succeeded, the controller determines the read level based on a result of comparison between the second frame data and a result of the correction process on the second frame data.

  • Patent number: 11910618
    Abstract: A configuration for efficiently placing a group of capacitors with one terminal connected to a common node is described. The capacitors are stacked and folded along the common node. In a stack and fold configuration, devices are stacked vertically (directly or with a horizontal offset) with one terminal of the devices being shared to a common node, and further the capacitors are placed along both sides of the common node. The common node is a point of fold. In one example, the devices are capacitors. N number of capacitors can be divided in L number of stack layers such that there are N/L capacitors in each stacked layer. The N/L capacitors are shorted together with an electrode (e.g., bottom electrode). The electrode can be metal, a conducting oxide, or a combination of a conducting oxide and a barrier material. The capacitors can be planar, non-planar or replaced by memory elements.
