摘要： Provided in the present disclosure are a flash memory array, and a write method and erasure method therefor. The flash memory array according to the present disclosure comprises : a plurality of flash memory cells, which are arranged in a row direction and a column direction perpendicular to the row direction; a plurality of word line groups, which extend in the row direction; and a plurality of bit line groups, which extend in the column direction, wherein flash memory cell pairs are arranged at intersection points of the word line groups and the bit line groups, and the flash memory cell pair comprises a first flash memory cell and a second flash memory cell, which are adjacent in the row direction and share the same bit line group. By means of the flash memory array according to the present disclosure, the arrangement density of bit lines can be improved while the size of the array is not increased, and the bit line parasitic resistance can be reduced. In addition, compared with a flash memory array in the prior art, the flash memory array according to the present disclosure also has a better process compatibility and scaling characteristic. The write method for a flash memory array of the present disclosure has the advantages of a low operation power consumption and a fast programming speed, which is conducive to improving the number of concurrently written flash memory cells, thereby increasing the data writing throughput rate of a memory. The erasure method for a flash memory array of the present disclosure can improve a threshold voltage window and enhance the storage reliability, and also has the advantages of a low operation power consumption and a fast erasure speed.

摘要： The present disclosure relates to a write driver and a method for operating the write driver for a memory device. The write driver is connected to a memory line of the memory device. Multiple memory cells of the memory device are connected to the memory line at different distances from the write driver. The operating method comprises controlling the write driver to provide a smaller amount of current for accessing a first memory cell of the memory cells, and controlling the write driver to provide a larger amount of current for accessing a second memory cell of the memory cells. Thereby, the first memory cell is connected to the memory line at a smaller distance to the write driver than the second memory cell.

摘要： Methods, systems, and devices for stacked memory dice and combined access operations are described. A device may include multiple memory dice. One die may be configured as a master, and another may be configured as a slave. The master may communicate with a host device. A slave may be coupled with the master but not the host device. The device may include a first die (e.g., master) and a second die (e.g., slave ). The first die may be coupled with a host device and configured to output a set of data in response to a read command. The first die may supply a first subset of the data and obtain a second subset of the data from the second die. In some cases, the first die may select, based on a data rate, a modulation scheme (e.g., PAM4, NRZ, etc.) and output the data using the selected modulation scheme.

摘要： A memory array with memory cells arranged in rows and columns. Each memory cell includes source and drain regions with a channel region there between, a floating gate disposed over a first channel region portion, and a second gate disposed over a second channel region portion. A plurality of bit lines each extends along one of the columns and is electrically connected to the drain regions of a first group of one or more of the memory cells in the column and is electrically isolated from the drain regions of a second group of one or more of the memory cells in the column. A plurality of source lines each is electrically connected to the source regions memory cells in one of the columns or rows. A plurality of gate lines each is electrically connected to the second gates of memory cells in one of the columns or rows.
