Description

記憶體單元及記憶體陣列
本發明是有關於一種記憶體單元,特別是一種能夠承受多次寫入操作的記憶體單元。
非揮發性記憶體(Non-volatile memory,NVM)是一種能夠在記憶體區塊無電源供應時,仍能保存儲存訊息的記憶體。
由於非揮發性記憶體能夠應用在各種領域中,因此將非揮發性記憶體嵌入於與主電路相同晶片的需求也成為趨勢,特別是在對於晶片空間要求嚴格的個人電子裝置應用中尤為普遍。
根據寫入次數限制的不同,非揮發性記憶體可分為多次寫入(multi-time programmable,MTP)記憶體和單次寫入(one-time programmable,OPT)記憶體。先前技術中的多次寫入非揮發性記憶體可包含用來儲存資料的浮接閘極電晶體,以及一或兩個用來致能浮接閘極電晶體以進行讀取、寫入及清除操作的選擇電晶體。為了透過電子注入或電子穿隧來寫入或清除記憶體單元,浮接閘極必須承受高電壓。在先前技術中,由於選擇電晶體是直接耦接至浮接閘極以利操作進行,因此選擇電晶體也需以製作耐高壓元件的高壓製程製作。然而,在高壓製程中,選擇電晶體會需要較大的面積,因此與目前縮減晶片面積的趨勢不符。此外,選擇電晶體所需的高導通電壓也會延長讀取操作的時間, 降低讀取操作的速度。
本發明之一實施例提供一種記憶體單元,記憶體單元包含寫入選擇電晶體、寫入元件、讀取選擇電晶體、讀取元件、共同浮接閘極及清除元件。
寫入選擇電晶體具有第一端、第二端、控制端及基極端,寫入選擇電晶體的第一端耦接於寫入源極線,寫入選擇電晶體的控制端耦接於寫入選擇線,而寫入選擇電晶體的基極端耦接於寫入控制線。寫入元件具有第一端、第二端及基極端,寫入元件的第一端耦接於寫入選擇電晶體之第二端,寫入元件的第二端耦接於寫入位元線,而寫入元件的基極端耦接於寫入控制線。讀取選擇電晶體具有第一端、第二端、控制端及基極端,讀取選擇電晶體的第一端耦接於讀取源極線,讀取選擇電晶體的控制端耦接於讀取選擇線,而讀取選擇電晶體的基極端耦接於偏壓控制線。讀取元件具有第一端、第二端及基極端,讀取元件的第一端耦接於讀取選擇電晶體之第二端,讀取元件的第二端耦接於讀取位元線,而讀取元件的基極端耦接於偏壓控制線。共同浮接閘極耦接於寫入元件及讀取元件。清除元件具有第一端、第二端及基極端,清除元件的第一端耦接於清除控制線,而清除元件的第二端耦接於共同浮接閘極。

第1圖為本發明一實施例之記憶體單元100的示意圖。記憶體單元100包含寫入選擇電晶體110、寫入元件120、讀取選擇電晶體130、讀取元件140、清除元件150及共同浮接閘極FG。
寫入選擇電晶體110具有第一端、第二端、控制端及基極端,寫入選擇電晶體110之第一端耦接於寫入源極線SLP,寫入選擇電晶體110之控制端耦接於寫入選擇線SGP,而寫入選擇電晶體110的基極端耦接於寫入控制線CLP。
寫入元件120具有第一端、第二端及基極端,寫入元件120之第一端耦接於寫入選擇電晶體110之第二端,寫入元件120之第二端耦接於寫入位元線BLP,而寫入元件120的基極端耦接於寫入控制線CLP。
讀取選擇電晶體130具有第一端、第二端、控制端及基極端,讀取選擇電晶體130之第一端耦接於讀取源極線SLR,讀取選擇電晶體130之控制端耦接於讀取選擇線SGR,而讀取選擇電晶體130的基極端耦接於偏壓控制線CLB。
讀取元件140具有第一端、第二端及基極端,讀取元件140之第一端 耦接於讀取選擇電晶體130之第二端,讀取元件140之第二端耦接於讀取位元線BLR,而讀取元件140的基極端耦接於偏壓控制線CLB。
清除元件150具有第一端及第二端,清除元件150之第一端耦接於清除控制線EL,清除元件150之第二端耦接於共同浮接閘極FG。
再者,清除元件150的第二端、寫入元件120的控制端及讀取元件140的控制端皆耦接於共同浮接閘極FG。
在此情況下,記憶體單元100主要是由寫入選擇電晶體110來選取進行寫入操作及清除操作,並由讀取選擇電晶體130選取進行讀取操作。也就是說,在寫入操作或清除操作中所需的高電壓不會直接施加於讀取選擇電晶體130。因此,讀取選擇電晶體130能夠以製作低耐壓元件的低壓製程來製作,而寫入選擇電晶體110、寫入元件120、清除元件150及讀取元件140則由製作高耐壓元件的高壓製程製作。
舉例來說,讀取選擇電晶體130的閘極氧化層厚度會小於寫入選擇電晶體110的閘極氧化層厚度,且寫入選擇電晶體110、寫入元件120、清除元件150及讀取元件140可具有實質上相同的閘極氧化層厚度。如此一來,寫入選擇電晶體110、寫入元件120、清除元件150及讀取元件140就能夠承受寫入操作及清除操作所需的高電壓,例如7V或甚至高於7V的電壓,而讀取選擇電晶體110則可利用例如為1.5V或甚至低於1.5V的低電壓來進行讀取操作。
第2圖為本發明一實施例之記憶體單元100的布局圖。在第2圖中,寫入選擇電晶體110及寫入元件120可由P型金氧半電晶體(P-type metal-oxide-semiconductors,PMOS)實作,而讀取選擇電晶體130、讀取元件140及清除元件150可由N型金氧半電晶體(N-type metal-oxide-semiconductors,NMOS)實作。
寫入選擇電晶體110及寫入元件120可利用N型井NW中的P型參雜區 P+來形成,且寫入選擇電晶體110及寫入元件120的基極端則可為N型井NW。此外,讀取選擇電晶體130、讀取元件140及清除元件150可利用P型井PW中的N型參雜區N+來形成。讀取選擇電晶體130及讀取元件140的基體端可為其P型井PW。然而,清除元件150的第一端可為P型井中的N型參雜區N+,因此施加於清除控制線EL的電壓並不會影響到讀取選擇電晶體130及讀取元件140。清除元件150還可包含基體端,清除元件150的基體端可為P型井PW。也就是說,讀取選擇電晶體130、讀取元件140及清除元件150的基體端可透過P型井互相連通。
此外,如第2圖所示,讀取元件140之主動區與共同浮接閘極FG重疊之重疊區域A1的面積可小於寫入元件120之主動區與共同浮接閘極FG重疊之重疊區域A2的面積。因此,共同浮接閘極EG的電壓主要會由寫入元件120所控制。
再者,由於讀取選擇電晶體130是以低壓製程製作,因此讀取選擇電晶體130可設置於與清除元件150不相鄰的位置,以避免讀取選擇電晶體130受到清除元件150所接收的高電壓影響而受損。
第3圖為記憶體單元100在寫入操作期間其訊號線所接收之電壓的示意圖。在記憶體單元100的寫入操作期間,寫入源極線SLP、寫入控制線CLP處於第一電壓VPP,寫入選擇線SGP及清除控制線EL處在介於第二電壓VDD及第三電壓VSS之間的電壓範圍,而寫入位元線BLP及偏壓控制線CLB處於第三電壓VSS。讀取源極線SLR、讀取選擇線SGR及讀取位元線BLR可為浮接狀態。第一電壓VPP大於第二電壓VDD,且第二電壓VDD大於第三電壓VSS。舉例來說,第一電壓VPP可為7.5V,第二電壓VDD可為5V,而第一電壓VSS可為地電壓,亦即0V。
在此情況下,寫入元件120的基極端會經由寫入控制線CLP接收到第一電壓VPP,且寫入選擇電晶體110會由寫入選擇線SGP所提供的低電壓導通。因此,耦合至共同浮接閘極FG的高電壓會造成通道熱電子注入。如此一來,電 子會被寫入元件120捕獲,因此記憶體單元100會被寫入。
此外,由於在寫入操作期間,讀取源極線SLR、讀取選擇線SGR及讀取位元線BLR皆處於浮接狀態,因此在寫入操作的過程中讀取選擇電晶體130及讀取元件140不會引致電流。
第4圖為記憶體單元100在清除操作期間其訊號線所接收之電壓的示意圖。在記憶體單元100的清除操作期間,寫入源極線SLP、寫入選擇線SGP、寫入位元線BLP及寫入控制線CLP可皆處於第三電壓VSS,而清除控制線EL可處於第四電壓VEE,第四電壓VEE大於第一電壓VPP。在部分實施例中,第一電壓VPP可為7.5V,而第四電壓VEE則可為15V。此外,偏壓控制線CLB可為第三電壓VSS、讀取源極線SLR、讀取選擇線SGR及讀取位元線BLR可皆為浮接狀態。
在此情況下,寫入元件120的基極端會經由寫入控制線CLP接收到第三電壓VSS,而寫入選擇電晶體110會被截止。此外,經由清除控制線EL,清除元件150會將共同浮接閘極FG耦合至高電壓。由於清除控制線EL處於第四電壓VEE,且第四電壓VEE較第一電壓VPP還要更高,所以在共同浮接閘極FG與清除控制線EL之間的巨大電壓差將造成福諾電子穿隧(Fowler-Nordheim tunneling)。因此,原先經由共同浮接閘極FG被寫入元件120捕獲電子會逃脫,使得記憶體單元100被清除。
此外,由於在清除操作期間,讀取源極線SLR、讀取選擇線SGR及讀取位元線BLR皆處於浮接狀態,因此在清除操作的過程中讀取選擇電晶體130及讀取元件140不會引致電流。
在部分實施例中,清除操作也可由負電壓來操作。第5圖為記憶體單元100在負壓清除操作期間其訊號線所接收之電壓的示意圖。在記憶體單元100的負壓清除操作期間,寫入源極線SLP、及寫入位元線BLP可處於第五電壓VBB,寫入選擇線SGP可處在介於第三電壓至第五電壓VBB減去寫入選擇電晶 體100之臨界電壓Vt之間的電壓範圍,亦即VSS至VBB-Vt之間的電壓,而寫入控制線CLP、清除控制線EL及偏壓控制線CLB可處於第三電壓VSS。第三電壓VSS可大於第五電壓VBB。也就是說,第五電壓VBB可為負電壓,例如為-15V,而第三電壓VSS可為地電壓。
此外,偏壓控制線CLB可處於第三電壓VSS,而讀取源極線SLR、讀取選擇線SGR及讀取位元線BLR可處於浮接狀態。
第6圖為記憶體單元100在讀取操作期間其訊號線所接收之電壓的示意圖。在記憶體單元100的讀取操作期間,寫入源極線SLP、寫入選擇線SGP、寫入位元線BLP、寫入控制線CLP、清除控制線EL及偏壓控制線CLB可皆處於第三電壓VSS。此外,讀取源極線SLR可處於第六電壓Vr,讀取選擇線SGR可處於第七電壓Vc,而讀取位元線BLR可處於第三電壓VSS。第七電壓Vc大於或等於第六電壓Vr,且第六電壓Vr大於第三電壓VSS。舉例來說,第七電壓Vc可為1.2V至1.5V,而第六電壓Vr可為1.2V。
在此情況下,讀取選擇電晶體130可被導通,並可根據共同浮接閘極FG的狀態產生讀取電流。舉例來說,若記憶體單元100被寫入,則電子將被寫入元件120捕捉。因此,共同浮接閘極EG將會處於相對的高電壓,進而產生讀取電流,並經由讀取位元線BLR輸出。相對地,若記憶體單元100並未被寫入,或是在寫入後已被清除,則將不會產生讀取電流。因此,根據讀取電流的強度就能夠判別出記憶體單元100中所儲存的資訊。
此外,讀取元件140和讀取選擇電晶體130是由N型電晶體實作,由於電子元件特性上的差異,因此記憶體單元100產生的讀取電流一般會大於利用P型電晶體實作之記憶體單元所產生的讀取電流。如此一來,記憶體單元100的讀取速度也能進一步提升。
然而,在本發明的其他實施例中,讀取選擇電晶體和讀取元件也可 利用P型電晶體來實作。第7圖為本發明另一實施例之記憶體單元200的示意圖。第8圖為本發明一實施例之記憶體單元200的布局圖。
記憶體單元200與記憶體單元100具有相同的結構,然而記憶體單元200之讀取選擇電晶體230及讀取元件240可由P型電晶體實作。
在第7圖中,寫入選擇電晶體110、寫入元件120、讀取選擇電晶體230及讀取元件240可皆設置於相同的N型井NW,而清除元件150則可由設置於P型井的N型電晶體實作。
在此情況下,由於以低壓製程製造的讀取選擇電晶體230與清除元件150可設置於相異的井區中,因此讀取選擇電晶體230可與清除元件150所接收之高電壓相隔離。
由於記憶體單元200之寫入選擇電晶體110、寫入元件120及清除元件150與記憶體單元100之寫入選擇電晶體110、寫入元件120及清除元件150有相同的構造及連接關係,因此第3至5圖中,各個訊號線於寫入操作期間、清除操作期間及負壓清除操作期間所接收到的電壓仍可應用於記憶體單元200以執行對應操作。
然而,由於讀取選擇電晶體230及讀取元件240為P型電晶體,因此在記憶體單元200的讀取操作期間,讀取源極線SLR可處於第七電壓Vc,讀取選擇線SGR可處於第三電壓VSS,而讀取位元線BLR可處於第六電壓Vr。第9圖為記憶體單元200在讀取操作期間其訊號線所接收之電壓的示意圖。
在此情況下,讀取選擇電晶體230會被導通,並可根據共同浮接閘極FG的狀態產生讀取電流。
由於記憶體單元100的讀取選擇電晶體130及記憶體單元200的讀取選擇電晶體230皆不會接收到高電壓,因此讀取選擇電晶體130及讀取選擇電晶體230可皆由製造低壓元件的低壓製程製作。因此讀取選擇電晶體的閘極氧化層 厚度會小於記憶體單元中其他電晶體的閘極氧化層厚度。如此一來,記憶體單元就能夠利用低電壓來執行讀取操作,因而簡化了讀取操作,同時也提升了讀取速度。
第10圖為本發明一實施例之記憶體陣列10的示意圖。記憶體陣列10包含N條寫入位元線BLP1至BLPN、M條寫入選擇線SGP1至SGPM、N條寫入控制線CLP1至CLPN,M條清除控制線EL1至ELM,N條寫入源極線SLP1至SLPN,N條讀取位元線BLR1至BLRN,M條讀取選擇線SGR1至SGRM,M條偏壓控制線CLB1至CLBM,N條讀取源極線SLR1至SLRN,以及M列的記憶體單元100(1,1)至100(1,N)、...、及100(M,1)至100(M,N)。其中M及N為正整數。
在第10圖中,每一個記憶體單元100(1,1)至100(1,N)、...、及100(M,1)至100(M,N)可與第1圖所示的記憶體單元100具有相同結構,且皆各自耦接於對應的控制線。
在部分實施例中,位於相同一列的記憶體單元會耦接於相同之寫入選擇線、相同之讀取選擇線、相同之偏壓控制線及相同之清除控制線。此外,位於相同一行之記憶體單元則會耦接於相同之讀取位元線、相同之讀取源極線、相同之寫入位元線、相同之寫入源極線及相同之寫入控制線。
舉例來說,記憶體單元100(1,1)及100(1,N)設置於相同一列。因此記憶體單元100(1,1)及100(1,N)會耦接至相同之寫入選擇線SGP1、相同之讀取選擇線SGR1、相同之偏壓控制線CLB1及相同之清除控制線EL1。相似地,記憶體單元100(M,1)及100(M,N)設置於相同一列。因此記憶體單元100(M,1)及100(M,N)會耦接至相同之寫入選擇線SGPM、相同之讀取選擇線SGRM、相同之偏壓控制線CLBM及相同之清除控制線ELM。
此外,記憶體單元100(1,1)及100(M,1)設置於相同一行。因此記憶體單元100(1,1)及100(M,1)會耦接至相同之讀取位元線BLR1、相同之讀取源極線 SLR1、相同之寫入位元線BLP1、相同之寫入源極線SLP1及相同之寫入控制線CLP1。相似地,記憶體單元100(1,N)及100(M,N)設置於相同一行。因此記憶體單元100(1,N)及100(M,N)會耦接至相同之讀取位元線BLRN、相同之讀取源極線SLRN、相同之寫入位元線BLPN、相同之寫入源極線SLPN及相同之寫入控制線CLPN。
在另一實施例中,記憶體陣列10的所有寫入控制線可互相耦接。又在另一實施例中,記憶體陣列10的所有清除控制線可互相耦接。
每一個記憶體單元100(1,1)至100(1,N)、...、及100(M,1)至100(M,N)可利用如第3至6圖之記憶體單元100所接收之訊號電壓來執行對應的寫入操作、清除操作、負壓清除操作及讀取操作。
綜上所述,本發明之實施例所提供的記憶體單元及記憶體陣列可包含用來執行讀取操作的讀取選擇電晶體及讀取元件。由於讀取選擇電晶體不須接收到高電壓,因此讀取選擇電晶體可利用低壓製程來製作。如此一來,記憶體單元及記憶體陣列就能夠利用低電壓訊號執行讀取操作,因而不僅簡化了讀取操作,也提升了讀取速度。以上所述僅為本發明之較佳實施例,凡依本發明申請專利範圍所做之均等變化與修飾,皆應屬本發明之涵蓋範圍。
