Therefore, advances in the fabrication of semiconductor memories including process enhancements and technology developments through the scaling for higher densities and faster speeds help establish performance standards for other digital logic families.

Semiconductor memory devices may be characterized as either volatile random access memories RAMsor non-volatile memory devices. In RAMs, the logic information is stored either by setting up the logic state of a bistable flip-flop such as in a static random access memory SRAMor through the charging of a capacitor as in a dynamic random access memory DRAM.

In either case, the data is stored and can be read out as long as the power is applied, and the data is lost when the power is turned off; hence, they are called volatile memories.

The non-volatile memory data storage mode may be permanent or reprogrammable, depending upon the fabrication technology used.

Non-volatile memories are used for program and microcode storage in a wide variety of applications in the computer, avionics, telecommunications, and consumer electronics industries.

A combination of single-chip volatile as well as non-volatile memory storage modes is also available in devices such as non-volatile SRAM nvSRAM for use in systems that require fast, programmable non-volatile memory.

In addition, dozens of special memory architectures have evolved which contain some additional logic circuitry to optimize their performance for application-specific tasks. Application of the EEPROM is widened to an auxiliary memory or to system programming where continuous update is needed.

A flash memory device includes a memory cell array that includes a number of memory blocks. The time required to erase memory blocks is a factor that limits the performance of a system that includes flash memory devices as well as a factor that limits the performance of the flash memory device itself.

To solve this drawback, a technique for simultaneously erasing a plurality of memory blocks is disclosed in patent publications US 5, on which the preamble of claim 1 is based and US 5, After simultaneously erasing a number of memory blocks, an erase verify operation is performed to judge whether the memory blocks have been normally erased.

Such an erase verify operation is made with respect to each of simultaneously erased memory blocks. With the above references, the erase verify operation is carried out by storing address information of erased memory blocks in a memory device and referring to the stored address information.

This means that a flash memory device requires separate control logic for controlling a multi-block erase verify operation and control signal lines related thereto. Accordingly, the erase verify operation of respective erased memory blocks is a factor that limits the performance and area of a flash memory device.

It is known as such to use a status register in a non-volatile semiconductor memory device for storing memory device status data and outputting them e. Laid-open publication GB 2 A1 discloses a method of simultaneously erasing the memory cells of a EEPROM followed by performing an erase verify operation, where erasing instructions are entered as data to an instruction register which generates appropriate control signals to the memory cells.An online information center for all who have Interest in Semiconductor Industry.
