    摘要: A novel FLASH-based EEPROM cell, decoder, and layout scheme are disclosed to eliminate the area-consuming divided triple-well in cell array and allows byte-erase and byte-program for high P/E cycles. Furthermore, the process-compatible FLASH cell for EEPROM part can be integrated with FLASH and ROM parts so that a superior combo, monolithic, nonvolatile memory is achieved. Unlike all previous arts, the novel combo nonvolatile memory of the present invention of ROM, EEPROM and FLASH or combination of any two is made of one unified, fully compatible, highly-scalable BN+cell and unified process. In addition, its cell operation schemes have zero array overhead and zero disturbance during P/E operations. The novel combo nonvolatile memory is designed to meet the need in those markets requiring flexible write size in units of bytes, pages and blocks at a lower cost.

    摘要: A nonvolatile memory device includes multiple independent nonvolatile memory arrays that concurrently for parallel reading and writing the nonvolatile memory arrays. A serial interface communicates commands, address, device status, and data between a master device and nonvolatile memory arrays for concurrently reading and writing of the nonvolatile memory arrays and sub-arrays. Data is transferred on the serial interface at the rising edge and the falling edge of the synchronizing clock. The serial interface transmits a command code and an address code from a master device and transfers a data code between the master device and the nonvolatile memory device, wherein the data code has a length that is determined by the command code and a location determined by the address code. Reading one nonvolatile memory array may be interrupted for reading another. One reading operation has two sub-addresses with one transferred prior to a command.

    摘要: In the present invention programming a plurality of MLC flash memory cells is done in parallel using a channel programming operation by applying a high positive voltage to a word line and positive voltages to the bit lines connected to cells to be programmed. The positive bit line voltages combined with the word line voltage create a channel voltage that is sufficient to program a required Vt level into each cell in parallel during a predetermined amount of time. Using a high positive word line voltage turns on the channel of a cell being programmed and eliminates potential breakdown condition, band to band tunneling current, channel pinch through and hole injection into the gate insulator, while allowing a small symmetrical cell that has low power consumption and a higher endurance cycle.

    摘要: In this invention a stacked gate flash memory cell is disclosed which has a lightly doped drain (LDD) on the drain side of the device and uses the source to both program using hot electron generation and erase the floating gate using Fowler-Nordheim-tunneling. Disturb conditions are reduced by taking advantage of the LDD and the biasing of the cell that uses the source for both programming and erasure. The electric field of the drain is greatly reduced as a result of the LDD which reduces hot electron generation. The LDD also helps reduce bit line disturb conditions during programming. A transient bit line disturb condition in a non-selected cell is minimized by preconditioning the bit line to the non-selected cell to Vcc.
