  • Patent number: 11956950
    Abstract: A method used in forming a memory array comprising strings of memory cells comprises forming laterally-spaced memory blocks individually comprising a vertical stack comprising alternating insulative tiers and conductive tiers. Channel-material strings of memory cells extend through the insulative tiers and the conductive tiers. The conductive tiers comprise metal along sides of the memory blocks. Silicon is formed between the memory blocks over the metal of the conductive tiers. The silicon and the metal react to form metal silicide therefrom that is directly against and longitudinally-along the metal of individual of the conductive tiers. After the reacting, unreacted of the silicon is removed from between the memory blocks and intervening material is formed between and longitudinally-along the memory blocks. Other embodiments, including structure independent of method, are disclosed.

  • Patent number: 11956955
    Abstract: A liner is formed laterally-outside of individual channel-material strings in one of first tiers and in one of second tiers. The liners are isotropically etched to form void-spaces in the one second tier above the one first tier. Individual of the void-spaces are laterally-between the individual channel-material strings and the second-tier material in the one second tier. Conductively-doped semiconductive material is formed against sidewalls of the channel material of the channel-material strings in the one first tier and that extends upwardly into the void-spaces in the one second tier. The conductively-doped semiconductive material is heated to diffuse conductivity-increasing dopants therein from the void-spaces laterally into the channel material laterally there-adjacent and upwardly into the channel material that is above the void-spaces.

A memory device may include a first cache may include a mapping table between the logical addresses and the physical addresses, and a second cache may include one or more descriptors of one or more physical addresses of the memory array. A descriptor may include a starting logical address, a starting physical address, and a quantity of addresses in the descriptor, and may be configured to identify addresses or sets of address that are frequently accessed. When an access command (e.g., a read command) is received, the first cache may be queried and then the second cache may be queried (if there is a cache miss at the first cache). The physical address of the data of the memory array may be determined (and accessed) based on the descriptors stored in the second cache.

  • Patent number: 11947840
    Abstract: Described systems, apparatuses, and methods relate to volatile memories that are refreshed to maintain data integrity, such as dynamic random-access memory (DRAM) and synchronous DRAM (SDRAM). A memory device includes multiple dies, with each die having a memory array to be refreshed. The multiple dies may be interconnected via at least one inter-die bus of the memory device. A memory controller sends a command to the memory device to enter a self-refresh mode. In response, a die of the multiple dies can enter the self-refresh mode and initiate or otherwise coordinate refresh operations of the other dies. To do so, the die may transmit at least one refresh-related command to at least one other die using the inter-die bus. Multiple different signaling schemes and timing approaches are disclosed. The described inter-die refresh control principles may be implemented in energy-efficient applications, such as in low-power double data rate (LPDDR) SDRAM.
