US 7,411,858 B2 · Dual-plane type flash memory device having random program function and program operation method thereof

Abstract

A dual-plane type flash memory device having a random program function and program operation method thereof. The flash memory device includes a first plane, a second plane, a first X-decoder, and a second X-decoder. The first plane includes first memory blocks sequentially arranged in a row direction. The second plane includes second memory blocks sequentially arranged in a row direction. The first X-decoder activates one of the first memory blocks in response to a first block address signal. The second X-decoder activates one of the second memory blocks in response to a second block address signal. The block activated by the first X-decoder of the first memory block is different from the block activated by the second X-decoder of the second memory blocks. Accordingly, during a program operation, memory blocks of two planes having different block addresses can be selected and programmed. Accordingly, the operational performance of the flash memory device can be enhanced.

Claims22

Dependent claims

A flash memory device comprising:

a first plane having first memory blocks sequentially arranged in a row direction;
a second plane having second memory blocks sequentially arranged in the row direction;
a first X-decoder for activating one of the first memory blocks in response to a first block address signal;
and
a second X-decoder for activating one of the second memory blocks in response to a second block address signal,
wherein, during a program operation, the block address of the first memory block activated by the first X-decoder is different from the block address of the second memory block activated by the second X-decoder.

3 more elements

A program operation method of a flash memory device, comprising the steps of:

storing first input data in a first page buffer unit included in a first plane;
activating one of a plurality of first memory blocks included in the first plane, said plurality of first memory blocks sequentially arranged in a row direction;
storing second input data in a second page buffer unit included in a second plane;
activating one of a plurality of second memory blocks included in the second plane, said plurality of second memory blocks and sequentially arranged in a row direction;
and
when one of the first memory blocks and one of the second memory blocks are activated, transmitting the first and second input data included in the first and second page buffer units to the activated first and second memory blocks,
wherein the block address of the activated first memory block is different from that of the activated second memory block.
