Semiconductor memory device and method for accessing a memory in the same

A method for accessing data in a memory cell in a semiconductor memory device having a plurality of memory cells divided into a plurality of memory blocks, the method comprising the steps of:

• putting a bit line and a virtual ground line connected to each of a plurality of first memory cells in one of the first memory blocks into a prechargeable state;
• putting a bit line and a virtual ground line connected to a second memory cell in a second memory block which needs to be accessed into an accessible state, and
• putting a bit line and a virtual ground line connected to at least one of the first memory cells in one of the first memory blocks which succeeds the second memory block into the accessible state while the second memory cell is being accessed.

A method for accessing data in a memory cell in a semiconductor memory device having a plurality of memory cells divided into a plurality of memory blocks, the method comprising the steps of:

• putting a bit line and a virtual ground line connected to a memory cell storing data included in a page to be accessed into an accessible state;
• and
• putting a bit line and a virtual ground line connected to a memory cell storing data included in other pages into a prechargeable state.
