Independent multi-plane read and low latency hybrid read
Read operations are performed in a multi-plane memory device. A state machine interfaces an external controller to each plane of memory cells to allow reading from selected word lines in the planes. In one approach, different types of read operations are performed in different planes, such as a multi-level cell read, e.g., a lower, middle or upper page read and a single-level cell (SLC) read. When the read operation in one plane uses fewer read voltages than another plane, the read data can be output early from the one plane while read operations continue on the other plane. The external controller can also command a cache release for one plane after outputting data from the caches of another plane. Read voltages can be set for each plane in a respective set of registers.
MEMORY POWER COORDINATION
The present disclosure includes apparatuses and methods related to bank coordination in a memory device. A number of embodiments include a method comprising concurrently performing a memory operation by a threshold number of memory regions, and executing a command to cause a budget area to perform a power budget operation associated with the memory operation.
SEMICONDUCTOR MEMORY DEVICE AND OPERATING METHOD THEREOF
Provided herein is a semiconductor memory device and an operating method thereof. The semiconductor memory device may include a memory cell array, a peripheral circuit, and a control logic. The memory cell array may include a plurality of memory blocks. The peripheral circuit may perform a program operation or read operation on a selected memory block of the memory cell array. The control logic may select between a first program method and a second program method depending on program mode information for the selected memory block, and may control the peripheral circuit to perform the program operation on the selected memory block using the selected program method.
MEMORY SUB-SYSTEM STORAGE MODE CONTROL
A system includes a memory device and a processing device coupled to the memory device. The memory device can include memory cells. The processing device can store operation system data in the memory cells in a single level cell (SLC) mode. The processing device can assert a flag indicating that the data written to the memory cells in the SLC mode is to remain stored in the SLC mode. The processing device can de-assert the flag, thereby indicating that the data is foldable into memory cells in a non-SLC mode.
Write operation techniques for memory systems
Methods, systems, and devices for write operation techniques for memory systems are described. In some memory systems, write operations performed on target memory cells of the memory device may disturb logic states stored by one or more adjacent memory cells. Such disturbances may cause reductions in read margins when accessing one or more memory cells, or may cause a loss of data in one or more memory cells. The described techniques may reduce aspects of logic state degradation by supporting operational modes where a host device, a memory device, or both, refrains from writing information to a region of a memory array, or inhibits write commands associated with write operations on a region of a memory array.
FeRAM-DRAM hybrid memory
Methods, systems, and devices for operating a ferroelectric memory cell or cells are described. One method includes determining whether to access a first memory cell of a first memory cell array or a second memory cell of a second memory cell array, where a first digit line coupled to the first memory cell is coupled to a paging buffer register including a sense amplifier. The method further includes operating a transfer gate based at least in part on determining to read the second memory cell of the second memory cell array, where the transfer gate is configured to selectively couple a second digit line coupled to the second memory cell to the paging buffer register through the first digit line.
TECHNIQUES FOR SATURATING A HOST INTERFACE
Methods, systems, and devices related to techniques for saturating a host interface are described. A set of data stored at a first memory device may be communicated over an interface during a read operation performed in response to receiving a read request associated with the set of data. A control component may determine if the interface entered an idle state during portions of the read operation. Based on detecting an idle state of the interface, the control component may transfer the set of data from the first memory device to a second memory device. After receiving a second read request for the set of data, the memory device may access the set of data from the second memory device and communicate the set of data over the interface, where the interface may remain in a saturated state throughout the second read operation.
METHOD AND APPARATUS TO PERFORM A READ OF A COLUMN IN A MEMORY ACCESSIBLE BY ROW AND/OR BY COLUMN
A memory accessed by rows and/or by columns in which an array of bits can be physically stored in multi-bit wide columns in physically contiguous rows is provided. A multi-bit wide logical column is arranged diagonally across (M/multi-bits) physical rows and (M/multi-bits) physical columns with each of the plurality of multi-bit wide logical columns in the logical row stored in a different physical row and physical multi-bit column.
SEMICONDUCTOR DEVICE
A semiconductor device including a FIFO circuit in which a data capacity can be increased while minimizing an increase in a circuit scale is provided. The semiconductor device includes a single-port type storage unit (11) which stores data, a flip-flop (12) which temporarily stores write data (FIFO input) or read data (FIFO output) of the storage unit (11), and a control unit (14, 40) which controls a write timing of a data signal, which is stored in the flip-flop (12), to the storage unit (11) or a read timing of the data signal from the storage unit to avoid an overlap between a write operation and a read operation in the storage unit (11).
