STREAMING MODE FOR ACCESSING MEMORY CELLS IN A MEMORY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17898346 titled 'STREAMING MODE FOR ACCESSING MEMORY CELLS IN A MEMORY DEVICE

Simplified Explanation

  • Memory device can selectively enter a streaming mode when accessing memory cells in a memory array.
  • Controller determines whether memory cells will be accessed in a streaming mode or random mode for new read operations.
  • First memory cells addressed using a wordline are read by the controller.
  • Wordline is charged to an initial voltage for reading the first memory cells.
  • In streaming mode, the wordline is not discharged after reading the first memory cells, but instead kept at a minimum bias and returned to initial voltage for the next read operation to read second memory cells.
  • This helps save power in the memory device.

Potential Applications

  • This technology can be applied in various memory devices such as solid-state drives, mobile devices, and computer systems.

Problems Solved

  • Reduces power consumption in memory devices.
  • Improves efficiency in accessing memory cells.

Benefits

  • Increased power efficiency.
  • Enhanced performance in memory access.
  • Extended battery life in mobile devices.


Original Abstract Submitted

Systems, methods, and apparatus for a memory device. In one approach, a memory device selectively enters a streaming mode when accessing memory cells in a memory array. A controller determines for new read operations whether memory cells will be accessed in a streaming mode or in a random mode. First memory cells addressed using a wordline are read by the controller. The wordline is charged to an initial voltage for reading the first memory cells. When in the streaming mode, instead of discharging the wordline after reading the first memory cells, as is done for a random mode, the controller keeps a minimum bias on the wordline and returns the wordline again to the initial voltage for performing a next read operation to read second memory cells. This saves memory device power.
