Reducing read disturbance overestimation

A memory system, comprising:

• one or more memory devices;
• and
• processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
• perform a first read operation at a first block of a first plane of a set of planes, wherein a respective first block of each plane of the set of planes is associated with a virtual block;
• set a first bit of a bitmap to a first value in response to performing the first read operation, wherein the bitmap is associated with the virtual block and wherein the first bit of the bitmap corresponds to the first block of the first plane of the set of planes;
• and
• determine whether to adjust a read counter associated with the virtual block in accordance with respective values of each bit of the bitmap.

A non-transitory computer-readable medium storing code comprising instructions which, when executed by one or more processors of a memory system cause the memory system to:

• perform a first read operation at a first block of a first memory die of a set of memory dies, a respective first block of each memory die of the set of memory dies being associated with a virtual block;
• set a first bit of a bitmap to a first value in response to performing the first read operation, wherein the bitmap is associated with the virtual block and wherein the first bit of the bitmap corresponds to the first block of the first memory die;
• and
• determine whether to adjust a read counter associated with the virtual block in accordance with respective values of each bit of the bitmap.
